[PATCH] extcon: usbc-tusb320: add USB_ROLE_SWITCH dependency

[PATCH] extcon: usbc-tusb320: add USB_ROLE_SWITCH dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_USB_ROLE_SWITCH=m, tusb320 cannot be built-in:

ld.lld: error: undefined symbol: fwnode_usb_role_switch_get
>>> referenced by extcon-usbc-tusb320.c
>>>               drivers/extcon/extcon-usbc-tusb320.o:(tusb320_probe) in archive vmlinux.a
ld.lld: error: undefined symbol: usb_role_switch_set_role
>>> referenced by extcon-usbc-tusb320.c
>>>               drivers/extcon/extcon-usbc-tusb320.o:(tusb320_state_update_handler) in archive vmlinux.a

Add the appropriate Kconfig dependency to prevent this
configuration but still allow the driver to be built-in
when USB_ROLE_SWITCH is disabled.
