this add functions for:
- remove buffers from src/dst queue by index
- remove exact buffer from src/dst queue
also extends m2m API to iterate over a list of src/dst buffers
in safely and non-safely manner.

* core.c has implemented the platform driver methods, file
operations and v4l2 registration.
* helpers.c has implemented common helper functions for:
- buffer management
- vb2_ops and functions for format propagation,
- functions for allocating and freeing buffers for
internal usage. The buffer parameters describing internal
buffers depends on current format, resolution and codec.
- functions for calculation of current load of the
hardware. Depending on the count of instances and
resolutions it selects the best clock rate for the video
core.

This is the implementation of HFI. It is charged with the
responsibility to comunicate with the firmware through an
interface commands and messages.
- hfi.c has interface functions used by the core, decoder
and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.
- hfi_cmds has packetization operations which preparing
packets to be send from host to firmware.
- hfi_msgs takes care of messages sent from firmware to the
host.

Here is the implementation of Venus video accelerator low-level
functionality. It contanins code which setup the registers and
startup uthe processor, allocate and manipulates with the shared
memory used for sending commands and receiving messages.

This adds Venus driver Makefile and changes v4l2 platform
Makefile/Kconfig in order to enable building of the driver.
Note that in this initial version the COMPILE_TEST-ing is not
supported because the drivers specific to ARM builds are still
in process of enabling the aforementioned compile testing.
Once that disadvantage is fixed the Venus driver compile testing
will be possible with follow-up changes.

Not sure what you're meaning here. Almost all media drivers for
ARM platforms build with COMPILE_TEST. The exceptions are some legacy
drivers that were added before COMPILE_TEST and rely on some weird
arch-specific functions (like arch-specific DMA functions like on OMAP3).
It is really important to make it build with COMPILE_TEST, as the
Coverity instance we use on Kernel works only for the code that builds
on x86. Also, on my test environment, I only do per-patch builds for
i386. So, if some patch breaks the build, I won't detect until too
late.
Btw, on a quick test, enabling compile-test on it built the driver
(I didn't make a full build - just a partial modules-only build - so
maybe it might depend on some qualcomm-specific symbols).
Building it with W=1 and gcc7 produced the following warnings:
drivers/media/platform/qcom/venus/hfi.c:171 hfi_core_ping() warn: inconsistent returns 'mutex:&core->lock'.

[PATCH] venus: enable building with COMPILE_TEST
We want all media drivers to build with COMPILE_TEST, as the
Coverity instance we use on Kernel works only for x86. Also,
our test workflow relies on it, in order to identify git
bisect breakages.
