OvmfPkg: install an SSDT with a dynamic OperationRegion called FWDT
"FWDT" ("firmware data") is allocated as EfiReservedMemoryType, with AllocateReservedPool(). <MdePkg/Include/Library/MemoryAllocationLib.h> doesn't seem to provide direct access to EfiACPIReclaimMemory, but at this point the former seems sufficient. Based on SeaBIOS commit 2062f2ba by Gerd Hoffmann <kraxel@redhat.com>. v3: - coding style fixes: - BDAT -> FWDT - __packed -> #pragma pack(1) - BFLD -> FIRMWARE_DATA, PCI_WINDOW - Bfld -> FwData - Ssdt.asl: changed license to 2-clause BSDL, paraphrasing Dsdt.asl Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@13573 6f19259b-4bc3-4df7-8a09-765794883524
