ARM: OMAP: N770: add missing LCD, LCD controller, touchscreen device registration 

These were left out from the board file when merging these drivers,
add them here.

Call GPIO init from the board file as well, since the platform device init
code uses the GPIO API.

Removed hwa742 init for now as it needs some clock updates.
