The Xen code in SmbiosPlatformDxe is centered on the informational HOB with GUID gEfiXenInfoGuid, and the address constants XEN_SMBIOS_PHYSICAL_ADDRESS=0x000EB000, XEN_SMBIOS_PHYSICAL_END=0x000F0000. This Xen hand-off mechanism is specific to the IA32 and X64 architectures, and it is very unlikely that a future ARM / AARCH64 implementation would follow it. Therefore, sequester the IA32 / X64 specific code from the rest of the source, by renaming "Xen.c" to "X86Xen.c", and adding a GetXenSmbiosTables() stub function in "ArmXen.c" that returns NULL. (Those file names are inspired by "OvmfPkg/Library/XenHypercallLib/X86XenHypercall.c".) The call site in SmbiosTablePublishEntry() [SmbiosPlatformDxe.c] is aware that a NULL return value means "Xen SMBIOS tables not found", and will continue to the QEMU tables (for which the retrieval mechanism is shared by x86 and Arm). This change enables SmbiosPlatformDxe for ARM architectures; update the VALID_ARCHITECTURES comment accordingly.
