sh: Fix up futex implementation.
SH is able to support a complete futex implementation on UP by way of gUSA. However, IRQ toggling must be done for the old CPUs that don't have movli.l/movco.l (LL/SC) instructions. Provide a default implementation that does this, so it's possible to optimize for newer CPUs. Follows the same scheme as the current asm-sh/atomic-*.h headers.
