rockchip: video: Add mipi display support for rk3399

This serials patches add mipi dsi support for rk3399. Except the basic mipi
driver, we need also enable pmic rk808 for lcd power and enable i2c for rk808
communication. what's more, the needed clk and pwm for backlight is init in
spl stage, make sure spl work first.

Add mipi dsi driver for rk chip. To enable this you need to enable DM, DM_VIDEO
DM_ROCKCHIP_VIDEO, DISPLAY_MIPI in menuconfig. And enable rk808 and it's i2c.

This looks pretty good to me but I think it needs another round.

Please can you split our this change a bit:

first patch: introduce your new Kconfig options (not the MIPI one
yet). Make sure that firefly-rk3288 and anything else that uses HDMI
still works. Same with boards that use EDP or LVDS. You will probably
need to add your new Kconfig options to their defconfig files

second patch: add the MIPI driver with its header file and
Makefile/Kconfig additions needed by the driver

third patch: rk_display_init() log2_bpp changes

fourth patch: change to plat->size

fifth patch: plumb driver into rv_vop.c and add the vop_rk3288.h change

Also make sure that the code is not compiled if CONFIG_VIDEO_ROCKCHIP
is not defined.
