3f61c80eb7 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.

022c03a2d6 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.
