This introduces InterruptController and HardwareTimer classes to handle the SoC specific implementations of timers and ints for the ARM platform.

These could be improved and moved to a more 'generic' level once we're confident they are 'good enough'.

NOTE: The OMAP timer implementation is fully untested and probably completely non-functional....
