ARM: local timers: Add A15 architected timer support Add support for the A15 generic timer and clocksource. As the timer generates interrupts on a different PPI depending on the execution mode (normal or secure), it is possible to register two different PPIs.

ARM: architected timers: Add A15 specific sched_clock implementation Provide an A15 sched_clock implementation using the virtual counter, which is thought to be more useful than the physical one in a virtualised environment, as it can offset the time spent in another VM or the hypervisor.
