usb: dwc2: Make PHY optional
Fixes commit 09a75e857790 ("usb: dwc2: refactor common low-level hw code to platform.c") The above commit consolidated the low-level phy access into a common location. This change introduced a check from the gadget requiring that a PHY is specified. This requirement never existed on the host side and broke some platforms when it was moved into platform.c. The gadget doesn't require the PHY either so remove the check.
