usb: gadget: max3420_udc: drop of_match_ptr for ID table

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here).

  drivers/usb/gadget/udc/max3420_udc.c:1312:34: error: ‘max3420_udc_of_match’ defined but not used [-Werror=unused-const-variable=]
