power: supply: pm8916_lbc: observe EXTCON config setting

When CONFIG_EXTCON=m and CONFIG_CHARGER_PM8916_LBC=y, there are
build errors. Fix them by having CHARGER_PM8916_LBC depend on the
setting of EXTCON.

aarch64-linux-ld: drivers/power/supply/pm8916_lbc.o: in function `pm8916_lbc_charger_state_changed_irq':
pm8916_lbc.c:(.text+0xe8): undefined reference to `extcon_set_state_sync'
