Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"

The appropriate include/asm-$ARCH directory should already by symlinked
to include/asm so using the whole "asm-$ARCH" path is unnecessary.

This change should also allow us to move the include/asm-$ARCH
directories into their appropriate lib/$ARCH/ directories.
