platform/x86: yt2-1380: add CONFIG_EXTCON dependency

This driver uses the extcon subsystem and fails to build
when it cannot call into that subsystem:

x86_64-linux-ld: vmlinux.o: in function `yt2_1380_fc_worker':
lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9d819): undefined reference to `extcon_get_state'
x86_64-linux-ld: lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9d853): undefined reference to `extcon_get_state'
x86_64-linux-ld: vmlinux.o: in function `yt2_1380_fc_serdev_probe':
lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9da22): undefined reference to `extcon_get_extcon_dev'
x86_64-linux-ld: lenovo-yoga-tab2-pro-1380-fastcharger.c:(.text+0xa9dc0c): undefined reference to `devm_extcon_register_notifier_all'

Add a Kconfig dependency to make it it always builds correctly.
