Davinci: gpio - controller type support
This patch allows for gpio controllers that deviate from those found on
traditional davinci socs. davinci_soc_info has an added field to indicate the
soc-specific gpio controller type. The gpio initialization code then bails
out if necessary.
More elements (tnetv107x) to be added later into enum davinci_gpio_type.
