Subject: [PATCH] power: supply: ucs1002: Fix build error without CONFIG_REGULATOR

Fix gcc build error while CONFIG_REGULATOR is not set

drivers/power/supply/ucs1002_power.o: In function `ucs1002_probe':
drivers/power/supply/ucs1002_power.c:593: undefined reference to `devm_regulator_register'
drivers/power/supply/ucs1002_power.o:(.rodata+0x3b8): undefined reference to `regulator_enable_regmap'
drivers/power/supply/ucs1002_power.o:(.rodata+0x3c0): undefined reference to `regulator_disable_regmap'
drivers/power/supply/ucs1002_power.o:(.rodata+0x3c8): undefined reference to `regulator_is_enabled_regmap'

Add Kconfig dependency to CONFIG_REGULATOR.
