power: supply: core: provide function stubs if CONFIG_POWER_SUPPLY=n
Fix build error when CONFIG_POWER_SUPPLY is not enabled.
The build error occurs in mips (cavium_octeon_defconfig).
mips-linux-gnu-ld: drivers/usb/dwc3/core.o: in function `dwc3_remove':
drivers/usb/dwc3/core.c:1657: undefined reference to `power_supply_put'
mips-linux-gnu-ld: drivers/usb/dwc3/core.o: in function `dwc3_get_properties':
drivers/usb/dwc3/core.c:1270: undefined reference to `power_supply_get_by_name'
mips-linux-gnu-ld: drivers/usb/dwc3/core.o: in function `dwc3_probe':
drivers/usb/dwc3/core.c:1632: undefined reference to `power_supply_put'
