[PATCH] platform/chrome: cros_ec_typec: Add a dependency on USB_ROLE_SWITCH

[Enric Balletbo i Serra]

As reported by the kernel test robot the cros_ec_typec driver fails to
build if the USB_ROLE_SWITCH is not selected, to fix that, add a
dependency on that symbol. This fixes the following build error:

   drivers/platform/chrome/cros_ec_typec.c:133: undefined reference to 
`usb_role_switch_put'
   ld: drivers/platform/chrome/cros_ec_typec.o: in function 
`cros_typec_get_switch_handles':
   drivers/platform/chrome/cros_ec_typec.c:108: undefined reference to 
`fwnode_usb_role_switch_get'
   ld: drivers/platform/chrome/cros_ec_typec.c:117: undefined reference to 
`usb_role_switch_put'

Fixes: 7e7def15fa4b ("platform/chrome: cros_ec_typec: Add USB mux control")
