Fix v4l2-compliance test bug and improve code quality of jpeg decode
driver, because the jpeg encode driver will base on it.

Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>

v6: alignment 'MTK_JPEG_DCTSIZE' match open parenthesis.
                                           
v5: Use clamp()to replace mtk_jpeg_bound_align_image() and round_up()
    to replace mtk_jpeg_align().
    Get correct compose value in mtk_jpeg_selection().
    Cancel spin lock and unlock operation in device run function.
    Change register offset hex numberals from upercase to lowercase.

v4: new add patch for v4l2-compliance test bug fix.

+* MediaTek JPEG Encoder
+
+MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs
+
+Required properties:
+- compatible : should be one of:
+               "mediatek,mt2701-jpgenc"
+               ...
+               followed by "mediatek,mtk-jpgenc"
+- reg : physical base address of the JPEG encoder registers and length of
+  memory mapped region.
+- interrupts : interrupt number to the interrupt controller.
+- clocks: device clocks, see
+  Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
+- clock-names: must contain "jpgenc". It is the clock of JPEG encoder.
+- power-domains: a phandle to the power domain, see
+  Documentation/devicetree/bindings/power/power_domain.txt for details.
+- mediatek,larb: must contain the local arbiters in the current SoCs, see
+  Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
+  for details.
+- iommus: should point to the respective IOMMU block with master port as
+  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+  for details.
+
+Example:
+	jpegenc: jpegenc@1500a000 {
+		compatible = "mediatek,mt2701-jpgenc",
+			     "mediatek,mtk-jpgenc";

Rename the files which are for decode feature. This is preparing
path since the jpeg enc patch will be added later.

Add mtk jpeg encode v4l2 driver based on jpeg decode, because that jpeg
decode and encode have great similarities with function operation.

Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>
---
v6: add space to arounding '+'.
    alignment 'struct mtk_jpeg_fmt *fmt' match open parenthesis.
    change 'mtk_jpeg_enc_set_encFormat' to 'mtk_jpeg_enc_set_enc_format'.
    make 'mtk_jpeg_ctrls_setup' to static prototype.
    delete unused variables 'jpeg'/'align_h'/'align_w'/'flags'.
    initialize 'yuv_format'/'enc_quality' variables.

v5: support crop for encoder and compose for decoder in s_selection and
    g_selection function.
    use clamp() to replace mtk_jpeg_bound_align_image() and round_up()
    to replace mtk_jpeg_align().
    delete jpeg_enc_param/mtk_jpeg_enc_param structure and
    mtk_jpeg_set_param(), program the registers directly based on
    the original V4L2 values.
    move macro definition about hw to mtk_jpeg_enc_reg.h.
    delete unnecessary V4L2 logs in driver.
    cancel spin lock and unlock operation in deviec run function.
    change jpeg enc register offset hex numberals from upercase to
    lowercase.
  
v4: split mtk_jpeg_try_fmt_mplane() to two functions, one for encoder,                                                      
    one for decoder.                                                          
    split mtk_jpeg_set_default_params() to two functions, one for                                                          
    encoder, one for decoder.                                                          
    add cropping support for encoder in g/s_selection ioctls.                                                          
    change exif mode support by using V4L2_JPEG_ACTIVE_MARKER_APP1.                                                         
    change MTK_JPEG_MAX_WIDTH/MTK_JPEG_MAX_HEIGH from 8192 to 65535 by                                                      
    specification.                                                          
    move width shifting operation behind aligning operation in                                                          
    mtk_jpeg_try_enc_fmt_mplane() for bug fix.                                                          
    fix user abuseing data_offset issue for DMABUF in                                                          
    mtk_jpeg_set_enc_src().                                                          
    fix kbuild warings: change MTK_JPEG_MIN_HEIGHT/MTK_JPEG_MAX_HEIGHT                                                      
                        and MTK_JPEG_MIN_WIDTH/MTK_JPEG_MAX_WIDTH from                                                      
                        'int' type to 'unsigned int' type.                                                          
                        fix msleadingly indented of 'else'.                                                          
                                                          
v3: delete Change-Id.                                                          
    only test once handler->error after the last v4l2_ctrl_new_std().                                                       
    seperate changes of v4l2-ctrls.c and v4l2-controls.h to new patch.

Thanks for the patch. The changes look good to me, but each of the
unrelated changes should be split into its own patch, with proper
explanation in its commit message. Especially the ones that introduce
behavior changes, such as the S_SELECTION or locking change.

Also please see one comment inline.

Why is it safe to remove the locking here?
