Subject: [RESEND v2 0/2] Modularize RPMH driver

Resending the patches rebasing on top of latest linux-next (next-20201002)

Changes in v2:
- Update commit message in patch 1
- send [4] again instead of revert's revert in patch 2.

This series is to modularize RPMH driver

The tracepoint in RPMH driver was changed to _rcuidle variant based on the
test results of unmerged series [1] where .power_off callback from genpd
reported RCU warnings. 

The series which finally got merged [2] uses CPU PM notifications
and genpd .power_off callback is not implemented in RPMH driver to invoke
rpmh_flush(). The CPU PM notifications are done with RCU non idle in kernel
(see cpu_pm_notify() uses rcu_irq_enter_irqson() before notifications)

However using _rcuidle variant prevented RPMH driver to compile as module
since these _rcuidle are not exported symbols for tracepoints.

This seris reverts the change [3] to remove _rcuidle variant for tracepoint
as its no more valid test case (genpd .power_off is not implemented)
and bring backs the change [4] that was reverted due to _rcuidle preventing
to become modular.
