extcon: cht_wc: add POWER_SUPPLY dependency
[ Upstream commit d20a3a8a32e3fa564ff25da860c5fc1a97642dfe ]
The driver fails to link when CONFIG_POWER_SUPPLY is disabled:
x86_64-linux-ld: vmlinux.o: in function `cht_wc_extcon_psy_get_prop':
extcon-intel-cht-wc.c:(.text+0x15ccda7): undefined reference to `power_supply_get_drvdata'
x86_64-linux-ld: vmlinux.o: in function `cht_wc_extcon_pwrsrc_event':
extcon-intel-cht-wc.c:(.text+0x15cd3e9): undefined reference to `power_supply_changed'
x86_64-linux-ld: vmlinux.o: in function `cht_wc_extcon_probe':
extcon-intel-cht-wc.c:(.text+0x15cd596): undefined reference to `devm_power_supply_register'
It should be possible to change the driver to not require this at
compile time and still provide other functions, but adding a hard
Kconfig dependency does not seem to have any practical downsides
and is simpler since the option is normally enabled anyway.
