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
