sh: Fixup movli.l/movco.l atomic ops for gcc4.

gcc4 gets a bit pissy about the outputs:

include/asm/atomic.h: In function 'atomic_add':
include/asm/atomic.h:37: error: invalid lvalue in asm statement
include/asm/atomic.h:30: error: invalid lvalue in asm output 1
...

this ended up being a thinko anyways, so just fix it up.

Verified for proper behaviour with the older toolchains, too.
