[PATCHv2 34/56] drm/omap: dsi: drop custom panel capability support

[Sebastian Reichel]

Due to previous changes the DSI encoder gets the capabilities
via DSI client's mode_flags and no longer needs the omapdss
specific caps. The core code now checks if the DSI encoder
is actually configured into command mode instead of just checking
the panel capabilities.
