Instead of accessing the LCDC channel and fb_info structures directly,
use the LCDC notification callback to inform the LCDC driver about
display-related events.
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The callback implements 3 notification events:
- SH_MOBILE_LCDC_EVENT_DISPLAY_CONNECT notifies the LCDC that the
display has been connected
- SH_MOBILE_LCDC_EVENT_DISPLAY_DISCONNECT notifies the LCDC that the
display has been disconnected
- SH_MOBILE_LCDC_EVENT_DISPLAY_MODE notifies that LCDC that a display
mode has been detected
