ARM: OMAP: don't build hwspinlock in vain

Cleanup: don't build mach-omap2/hwspinlock.c if the OMAP hwspinlock driver isn't configured.

This will both shorten build time and avoid registering a device which isn't needed.

Tony, it's probably better if you take it, to minimize omap merge conflicts. Thanks!
