[PATCH] regulator: act8865: Fix build error without CONFIG_POWER_SUPPLY

[YueHaibing]

Building without CONFIG_POWER_SUPPLY will fail:

drivers/regulator/act8865-regulator.o: In function `act8865_pmic_probe':
act8865-regulator.c:(.text+0x357): undefined reference to `devm_power_supply_register'
drivers/regulator/act8865-regulator.o: In function `act8600_charger_get_property':
act8865-regulator.c:(.text+0x3f1): undefined reference to `power_supply_get_drvdata'

Add POWER_SUPPLY dependency to Kconfig.
