davinci: Add LCD Graphics support for DA830/OMAP-L137 EVM
Add graphics support for the Sharp LCD035Q3DG01 graphical
LCD that's on the User Interface (UI) daughter card of the
DA830/OMAP-L137 EVM.
The LCD shares EMIFA lines with the NAND and NOR devices that
are also on the UI card so those lines are shared via a couple
of muxes. The muxes are controlled by the 'MUX_MODE' line on
the UI card. The 'MUX_MODE' line is controlled by pin P6 of
a pcf8574 i2c expander that's at i2c address 0x3f on UI card.
The i2c expander is controlled using the gpio infrastructure
from the board code using the 'setup()' and 'teardown()'
routines.
