[PATCH 2/3] pmdomain: amlogic: Add support for A5 power domains controller

[Xianwei Zhao via B4 Relay <devnull+xianwei.zhao.amlogic.com@kernel.org>]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Add support for the A5 power controller, whose registers are
in the secure domain and should be accessed via SMC.
