meta-ampere: mtjade: initialize GPIOs

Several GPIOs should be configured properly when booting BMC. Currently,
these GPIOs are configured in u-boot. However, some must be configured
in Linux. For example, the BMC_READY GPIO should be set only after BMC
is ready to work.
This commit introduce platform-init service which starts after BMC boots
to configure GPIOs pins required by hardware design.

Tested:
1. Do A/C power, check GPIO227 is set to 0.
2. Reboot BMC, check GPIO227 is set to 0.
3. Run gpioinfo and check GPIO directions
