[ARM] 4530/1: MXC: fix elf_hwcap compile breakage as in iop13xx

MXC needs the same change as IOP.  See [ARM] 4494/1
or commit 7dea1b20

An undefined reference to elf_hwcap prevents linkage, due
to changes made by f884b1cf
and d1cbbd6b

Removing processor.h removes the extern definition of
elf_hwcap, which fixes the link issue, but forgets cpu_relax().
So, instead, we'll call barrier() directly.
