Before invoking the arch specific handler, efi_mem_reserve() reserves the given memory region through memblock. efi_bgrt_init() will call efi_mem_reserve() after mm_init(), at which time memblock is dead and should not be used anymore. The EFI BGRT code depends on ACPI initialization to get the BGRT ACPI table, so move parsing of the BGRT table to ACPI early boot code to ensure that efi_mem_reserve() in EFI BGRT code still use memblock safely.
