usb: dwc3: Update DWC_usb31 GTXFIFOSIZ reg fields

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 | +-------+-----------+----------------------------------+ Signed-off-by: Thinh Nguyen <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>
