[U-Boot] [PATCH 3/3] imx: Define a common header file for gpio.h

[Vikram Narayanan <vikram186@gmail.com>]

Remove redundant gpio_regs structure for every board and define a
common header for gpio_regs in the drivers/gpio directory. All the
board files needs to be changed to point to asm-generic/gpio.h
for gpio_* functions.
