Currently only OMAP4 supports hwspinlocks, so don't bother asking

Add hwspinlock support for the OMAP4 Hardware Spinlock device.
The Hardware Spinlock device on OMAP4 provides hardware assistance
for synchronization between the multiple processors in the system
(dual Cortex-A9, dual Cortex-M3 and a C64x+ DSP).[ohad@wizery.com: adapt to hwspinlock framework, tidy up]

Add a platform-independent hwspinlock framework.
Hardware spinlock devices are needed, e.g., in order to access data
that is shared between remote processors, that otherwise have no
alternative mechanism to accomplish synchronization and mutual exclusion
operations.Signed-off-by: Ohad Ben-Cohen
