meta-ampere:mtjade:u-boot: Add GPIO support
This is an initial support for the parallel GPIO pins directly connected
to the AHB on the Aspeed 2400/2500.
This brings the functions and a shell command to manipulate the GPIO
state. The GPIO value reading and writing work in non interrupt mode
only.
This is back ported from the patch file from
meta-yadro/meta-nicole/recipes-bsp/u-boot/files/0003-aspeed-add-gpio-support.patch
to support GPIO configuration
