OMAP: DSS2: DSI Video mode support
Add initial support for DSI video mode panels:
- Add a new structure omap_dss_dsi_videomode_data in the member "panel" in
omap_dss_device struct. This allows panel driver to configure dsi video_mode
specific parameters.
- Configure basic DSI video mode timing parameters: HBP, HFP, HSA, VBP, VFP, VSA,
TL and VACT.
- Configure DSI protocol engine registers for video_mode support.
- Introduce functions dsi_video_mode_enable() and dsi_video_mode_disable() which
enable/disable video mode for a given virtual channel and a given pixel format
type.
Things left for later
- Add functions to check for errors in video mode timings provided by panel.
- Configure timing registers required for command mode interleaving.
