fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().

UEFI on ARM requires that unaligned memory access is enabled.

* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
  U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
  which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
  For none of the other cpus in arch/arm/cpu/ we have implemented a
  similar function.
* ARMv8 allows unaligned access.

Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.

Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.
