Hello!
This patch set adds support (driver and sm functions) for working with
power domain controller using secure monitor for Amlogic A1-series.
Additionally, in the future, the driver can be used for other Amlgoic
SoC series, such as S4.

This is necessary so that pwrc can be used together with
peripherals when described in a bus node. For example,
in the future, this will be USB.
