efi_memory: do not add RAM memory to the memory map

The EFI_CONVENTIONAL_MEMORY type, which is the usable RAM memory is
now being managed by the LMB module. Remove the addition of this
memory type to the EFI memory map. This memory now gets added to the
EFI memory map as part of the LMB memory map update event handler.
