usb: mtu3: fix EXTCON dependency
When EXTCON is a loadable module, mtu3 fails to link as built-in:
drivers/usb/mtu3/mtu3_plat.o: In function `mtu3_probe':
mtu3_plat.c:(.text+0x690): undefined reference to `extcon_get_edev_by_phandle'
Add a Kconfig dependency to force mtu3 also to be a loadable module
if extconn is, but still allow it to be built without extcon.
Fixes: d0ed062a8b75 ("usb: mtu3: dual-role mode support")
