Davinci: gpio - register layout invariant inlines
This patch renders the inlined gpio accessors in gpio.h independent of the
underlying controller's register layout. This is done by including three new
fields in davinci_gpio_controller to hold the addresses of the set, clear, and
in data registers.
Other changes:
1. davinci_gpio_regs structure definition moved to gpio.c. This structure is
no longer common across all davinci socs (davinci_gpio_controller is).
2. controller base address calculation code (gpio2controller()) moved to
gpio.c as this was no longer necessary for the inline implementation.
3. modified inline range checks to use davinci_soc_info.gpio_num instead of
DAVINCI_N_GPIO.
