Davinci: gpio - structs and functions renamed
Renamed gpio types to something more sensible:
struct gpio_controller --> struct davinci_gpio_regs
struct davinci_gpio --> struct davinci_gpio_controller
gpio2controller() --> gpio2regs()
irq2controller() --> irq2regs()
This change also moves davinci_gpio_controller definition to gpio.h.
Eventually, the gpio registers structure will be moved to gpio.c and no longer
a common cross-soc definition.
