ARM64: rockchip: syr82x: support syr82x regulator

Browse Source 
Add suspend/resume enable/disable setting function.
Silergy SYR82x regulators share the exact same functionality and register
layout as the Fairchild FAN53555 regulators.
The fan53555 is upstreamed.
Therefore use fan53555.c for support syr82x.
