usb: dwc3: gadget: Add missing check for single port RAM in TxFIFO resizing logic

The existing implementation of the TxFIFO resizing logic only supports
scenarios where more than one port RAM is used. However, there is a need
to resize the TxFIFO in USB2.0-only mode where only a single port RAM is
available. This commit introduces the necessary changes to support
TxFIFO resizing in such scenarios by adding a missing check for single
port RAM.

This fix addresses certain platform configurations where the existing
TxFIFO resizing logic does not work properly due to the absence of
support for single port RAM. By adding this missing check, we ensure
that the TxFIFO resizing logic works correctly in all scenarios,
including those with a single port RAM.
