MLK-22878 usb: cdns3: gadget: add imx8qxp C0 support

We use controller version to differetiate between B0 (0x00024502)
and C0 (0x0002450C). The controller uses TDL check to
avoid "NO NAK" issue at B0 if there is not buffer for OUT, this issue
is described at "Work around 2" at the begin of gadget.c

At default, the TDL value is 0, so it always NAK host's OUT token.
When the TD is added, the TDL value is non-zero, it will respond
NAK/ACK according to OUT FIFO's situation.
