usb: dwc2: add external_id_pin_ctl core parameter
This is required due to an Intel specific hardware issue. Where id-
pin setup causes glitches on the interrupt line when CONIDSTSCHG
interrupt is enabled.
Specify external_id_pin_ctl when an external driver (for example phy)
can handle id change, so that CONIDSTSCHG interrupt can be disabled
from the controller.
