Resource State Coordinator (RSC) is responsible for powering off/lowering
the requirements from CPU subsystem for the associated hardware like buses,
clocks, and regulators when all CPUs and cluster is powered down.

RSC power domain uses last-man activities provided by genpd framework based on
Ulf Hansoon's patch series[1], when the cluster of CPUs enter deepest idle
states. As a part of domain poweroff, RSC can lower resource state requirements
by flushing the cached sleep and wake state votes for resources.
