TI: DaVinci: GPIO header file and definitions

Browse Source 
Some DaVinci SOC's use GPIOs to enable EMAC and DM9000.
This patch adds some definitions for GPIO registers and also adds
structures for GPIO.
A separate header file is being added so that in future we
can have a DaVinci GPIO driver similer to OMAP.
