Switch the historical OvmfPkg* platforms from the AcpiPlatformDxe driver to the QemuFwCfgAcpiPlatformDxe driver. (The latter is used by the ArmVirtQemu* platforms as well.)
The change effectively replaces the following call tree: InstallAcpiTables [AcpiPlatform.c] XenDetected [XenPlatformLib] * InstallXenTables [Xen.c] * GetXenAcpiRsdp [Xen.c] * InstallQemuFwCfgTables [QemuFwCfgAcpi.c] ... InstallOvmfFvTables [AcpiPlatform.c] * QemuDetected [Qemu.c] * LocateFvInstanceWithTables [AcpiPlatform.c] * QemuInstallAcpiTable [Qemu.c] * QemuInstallAcpiMadtTable [Qemu.c] * CountBits16 [Qemu.c] * QemuInstallAcpiSsdtTable [Qemu.c] * GetSuspendStates [Qemu.c] * PopulateFwData [Qemu.c] * with the one below: InstallAcpiTables [QemuFwCfgAcpiPlatform.c] InstallQemuFwCfgTables [QemuFwCfgAcpi.c] ... eliminating the sub-trees highlighted with "*". There are two consequences: (1) Xen compatibility is removed from the ACPI platform driver of the historical OvmfPkg* platforms. (2) The ACPI tables that are statically built into OVMF (via "OvmfPkg/AcpiTables/AcpiTables.inf") are never installed. In particular, OVMF's own runtime preparation of the MADT and SSDT is eliminated. Because of (2), remove the "OvmfPkg/AcpiTables/AcpiTables.inf" module as well -- and then the ACPITABLE build rule too. Note that (2) only removes effectively dead code; the QEMU ACPI linker-loader has taken priority since QEMU 1.7.1 (2014).
