usb: dwc3: Update DWC_usb31 GTXFIFOSIZ reg fields

[ Upstream commit 0cab8d2 ]

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                     |
 +-------+-----------+----------------------------------+
