[PATCH v7 0/7] dw-hdmi: convert imx hdmi to bridge/dw-hdmi

[Andy Yan]

We found freescale imx5 and rockchip rk3288 and Ingenic JZ4780 (Xburst/MIPS)
use the interface compatible Designware HDMI IP, but they also have some
lightly differences, such as phy pll configuration, register width(imx hdmi
register is one byte, but rk3288 is 4 bytes width and can only access by word),
4K support(imx6 doesn't support 4k, but rk3288 does).

To reuse the imx-hdmi driver, we do this patch set:
(1): fix some CodingStyle warning to make checkpatch happy
(2): split out imx-soc code from imx-hdmi to dw_hdmi-imx.c
(3): move imx-hdmi to bridge/dw-hdmi, and convert it to a drm_bridge driver
And we will add rockchip platform specific code dw_hdmi-rockchip.c later,
which is depend on drm-rockchip.

Changes in v7:
- remove unused variables from structure dw_hdmi
- remove a wrong modification
- add copyrights for dw_hdmi-imx.c

Changes in v6:
- rearrange the patch order
- move some modification to  patch#6
- refactor register access without reg_shift
- move some modification from patch#5

Changes in v5:
- refactor reg-io-width

Changes in v4:
- fix checkpatch CHECK
- defer probe ddc i2c adapter

Changes in v3:
- split multi register access to one indepent patch

Changes in v2:
- use git format -M to generate these patch
