From: Sudeep KarkadaNagesha <sudeep.karkadanagesha at arm.com>

This patch series adds support to configure the rate and enable the event
stream for architected timer. Since the timer control register is reset to
zero on warm boot, CPU PM notifier is added to re-initialse it.

Changes v1->v2:
1. Saved event stream divider value on cold reset path and re-used it
   in CPU PM notifier instead of calculating every time.
2. Rebased on v3.11-rc2(to avoid conflicts with __cpuinit* deletion)
3. Dropped "ARM/ARM64: arch_timer: remove __cpuinit attribute for
   arch_counter_set_user_access"(already done as part of __cpuinit*
   deletion)

Regards,
Sudeep
