ENGR00209899-1 mx6x: add generic gpio interface.
Add generic gpio interface in uboot.
Seems more and more gpio operation invoke in uboot,
without RAW register operation, we should
use generic gpio interface.
you should define the CONFIG_MXC_GPIO
use generic gpio interface:
gpio_request,
gpio_direction_output,
gpio_direction_input,
gpio_set_value,
gpio_get_value, etc.
Test on MX6Q, MX6DL.
Other MX6X should also define this config.
