Since the function is simple and only called during initialization and power management state transitions, the wrapper is unnecessary. Remove it and inline the regmap_update_bits() logic directly at the call sites to improve code readability and traceabilty. Where applicable, introduce a local 'map' pointer to keep the inlined function calls concise.
