[PATCH 2/2] clk: spacemit: register pm domain auxiliary driver

[Yixun Lan]

The APMU (Application Subsystem Power Management Unit) register region
block contains the pm domain management capabilities, introduce a pm_name
member inside CCU data to register a pm domain device via the auxiliary
bus if that is needed - if pm_name is null, no device is registered.
