Pull (mostly) ARM clocksource driver updates from Daniel Lezcano:
" - Soren Brinkmann added FEAT_PERCPU to a clock device when it is local
per cpu. This feature prevents the clock framework to choose a per cpu
timer as a broadcast timer. This problem arised when the ARM global
timer is used when switching to the broadcast timer which is the case
now on Xillinx with its cpuidle driver.
- Stephen Boyd extended the generic sched_clock code to support 64bit
counters and removes the setup_sched_clock deprecation, as that causes
lots of warnings since there's still users in the arch/arm tree. He
added also the CLOCK_SOURCE_SUSPEND_NONSTOP flag on the architected
timer as they continue counting during suspend.
- Uwe Kleine-König added some missing __init sections and consolidated the
code by moving the of_node_put call from the drivers to the function
clocksource_of_init. "
