We did implement regmap in the acpi opregion driver(see drivers/acpi/pmic
for details) for the PMIC device. Each individual driver, e.g. gpio,
thermal, etc. will only access registers that belong to its logic unit.
Since the shared regmap implementation is already there, a single individual
driver doesn't need to implement again.
