[PATCH 04/43] OvmfPkg: switch the AmdSev platform to the fw_cfg-only ACPI platform driver

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

For consistency with the historical OvmfPkg* platforms, switch the
remotely attested, QEMU/KVM-only, AmdSev platform from the AcpiPlatformDxe
driver to the QemuFwCfgAcpiPlatformDxe driver.

No module remains dependent on XenPlatformLib, so remove the
XenPlatformLib class resolution too, from the DSC file.
