The pinmux which got added is based on the venice2 pinmux spreadsheet 
where I covered only the SFIO pin groups.

After comparing with the chrome, I also added the pinmux for all pins 
which are used as GPIO and hence the change is big.
This is complete pinmux based on chrome kernel-next.
I booted chrome with this pinmux and not observe any behavioral change.
