arch: Clean up asm/barrier.h implementations using asm-generic/barrier.h
We're going to be adding a few new barrier primitives, and in order to
avoid endless duplication make more agressive use of
asm-generic/barrier.h.
Change the asm-generic/barrier.h such that it allows partial barrier
definitions and fills out the rest with defaults.
There are a few architectures (m32r, m68k) that could probably
do away with their barrier.h file entirely but are kept for now due to
their unconventional nop() implementation.
