sh_mobile_lcdc: Add display notify callback to sh_mobile_lcdc_chan
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 Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
