usb: dwc3: Update DWC_usb31 GTXFIFOSIZ reg fields
[ Upstream commit 0cab8d26d6e5e053b2bed3356992aaa71dc93628 ]
Update two GTXFIFOSIZ bit fields for the DWC_usb31 controller. TXFDEP
is a 15-bit value instead of 16-bit value, and bit 15 is TXFRAMNUM.
The GTXFIFOSIZ register for DWC_usb31 is as follows:
+-------+-----------+----------------------------------+
| BITS | Name | Description |
+=======+===========+==================================+
| 31:16 | TXFSTADDR | Transmit FIFOn RAM Start Address |
| 15 | TXFRAMNUM | Asynchronous/Periodic TXFIFO |
| 14:0 | TXFDEP | TXFIFO Depth |
+-------+-----------+----------------------------------+
