meta-ampere: mtjade: add mtjade-gpio-config package

The OCP module in Mt.Jade platform supports the GPIO pins to set the
power state. The SPI0 module also supports the GPIO pins to config SPI
mode. These gpio pins have to be set to the right states before power
off/on. The mtjade-gpio-config package will support that.

Tested:
    1. Power off/on the host.
    2. The OCP and SPI0 gpio pins should be in the corrected states.
