usb: dwc3: Check for USB4 IP_NAME
commit 0ed91d47959cb7573c17e06487f0fb891d59dfb3 upstream.
Synopsys renamed DWC_usb32 IP to DWC_usb4 as of IP version 1.30. No
functional change except checking for the IP_NAME here. The driver will
treat the new IP_NAME as if it's DWC_usb32. Additional features for USB4
will be introduced and checked separately.
