meta-ampere: mtjade: support PSU present detection via GPIO

It checks GPIO key for powersupply presence, and creates
the inventory object.

Tested:
1. Plug the PSU, check busctl command for Present attribute
2. Plug out the PSU, check busctl command for Present attribute
$ busctl --no-pager introspect xyz.openbmc_project.Inventory.Manager
/xyz/openbmc_project/inventory/system/chassis/motherboard/powersupply0
