usb: dwc3: Add new updates for DWC_usb31

This patch series adds new updates and some fixes for DWC_usb31.

Changes in v3:
- Add "usb: dwc3: Check controller type before setting speed" to series

Changes in v2:
- Add another patch to the series to increase mass_storage max_speed
- Separate "usb: dwc3: ep0: Reset TRB counter for ep0 IN" from series
- Separate "usb: dwc3: gadget: Set maxpacket size for ep0 IN" from series
- Use msleep() instead of mdelay() for SoftReset PHY sync delay
- Rename new USB31 macros from DWC3_USB31_* to DWC31_*
- Rename device properties and replace '_' with '-'
- Minor fixes in the commit messages

DWC_usb31 periodic transfer at 48K+ bytes per interval may need modification to the TX/RX packet threshold to achieve optimal result. Add properties to make it configurable.

Hi,

By default, periodic ESS TX and RX threshold are not enabled. To enable TX or RX threshold, both packet threshold count and max burst size must be set to a non-zero value.

Unfortunately, I did not document it in this file after I made a change to remove the enabling of TX/RX threshold property. I can update this patch series with this information. Thanks.

BR,
Thinh

In DWC_usb31 version 1.70a-ea06 and prior needs a SW workaround for isoc START TRANSFER command failure. However, some affected versions may have RTL patches to fix this without a SW workaround. Add this quirk to disable the SW workaround when it is not needed.
