The correct load order for the NOR Flash driver and Runtime Variables
to work is as below:
    1. Arm CPU Architecture Protocol Dxe
    2. NOR Flash Dxe
    3. Runtime Variable Dxe

NvVarStoreFormattedLib was recently introduced to resolve the dependency
order and more details can be seen at
https://github.com/tianocore/edk2/compare/master...lersek:depex_fixes

This patch propagates the necessary changes for ARM Juno platform and
also fixes the "Firmware Volume for Variable Store is corrupted" error
seen when the Flash is erased (or not formatted).
