Heinrich Schuchardt c3b11dea7c efi_loader: allow unaligned memory access
The UEFI spec mandates that unaligned memory access should be enabled if
supported by the CPU architecture.

This patch adds an empty weak function unaligned_access() that can be
overridden by an architecture specific routine.
