Rambi: Set SOC_DISP_ON as GPIO to avoid LCD_VCC glitch
To avoid LCD_VCC glitch on cold reset, set SOC_DISP_ON as GPIO output high.
After gfx initialize is done, set it to native function 2.
BUG=chrome-os-partner:25159
BRANCH=firmware-rambi-5216.B
TEST=Tested on Rambi and squawks, no LCD_VCC glitch anymore.
