ARMv4: Add a minimal version of cpu.h.

All this version does is define asmlinkage to be nothing. It's required by the
threading header file which is brought in by the timer implementation which I
think is the hook for thread switching.

BUG=None
TEST=Built with Ron's patch which adds some clock functions and saw the
compile error go away.
BRANCH=None
