[PATCH 6/7] ArmVirtPkg/QemuFwCfgLib: allow UEFI_DRIVER modules

["Laszlo Ersek" <lersek@redhat.com>]

We don't distribute UEFI_DRIVER modules stand-alone that were built as
part of an ArmVirtQemu* platform. ArmVirtQemu* UEFI_DRIVERs are allowed to
inherit platform dependencies.

By enabling UEFI_DRIVERs to consume QemuFwCfgLib, we can hook fw_cfg-based
NULL class libraries into UEFI drivers, e.g. in order to set dynamic PCDs.
