[RESEND PATCHv5] usb: dwc2: Add function to calculate correct FIFO sizes

From: Dinh Nguyen The dwc2 IP on the SOCFPGA cannot use the default HW configured FIFO sizes. The total FIFO depth as read from GHWCFG3 reports 0x1f80 or 8064 32-bit words. But the GRXFSIZ, GNPTXFSIZ, and HPTXFSIZ register defaults to 0x2000 or 8192 32-bit words. So the driver cannot just use the
