usb: rockusb: Add support for usb3 download

This patch improve the usb gadget drivers and the usb
dwc3 controller drivers to support rockusb usb3 download
images.

With this patch, it can support:
1. Maskrom usbplug usb2 switch to usb3 automatically
if the boards and the upgrade tool support usb3.

2. Loader enter usb3 automatically if the boards support usb3.

3. Force Maskrom/Loader usb fall back to usb2 if wait
for usb3 enumeration time out.

In the 3.0 device core, if the core is programmed to operate in
2.0 only, then setting the GUCTL1.DEV_FORCE_20_CLK_FOR_30_CLK makes
the internal 2.0(utmi/ulpi) clock to be routed as the 3.0 (pipe)
clock. Enabling this feature allows the pipe3 clock to be not-running
when forcibly operating in 2.0 device mode.

UPSTREAM: usb: dwc3: Fix UTMI/UTMIW phy interface initialization

DWC3 support phy interfaces like 8/16-bit UTMI+. phy interface
initialization code would handle them properly along with UNKNOWN
type by default if none of the user/board doesn't need to use the
phy interfaces at all.

The current code is masking the 8/16-bit UTMI+ interface bits globally
which indeed effect the UNKNOWN cases, therefore it effects the platforms
which are not using phy interfaces at all.

So, handle the phy masking bits accordingly on respective interface
type cases.

UPSTREAM: usb: dwc3: Add phy interface for dwc3_uboot

U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
call dwc3_uboot_init in core.

The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.

So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.

This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.

This change used Linux phy.h enum list, to make proper code
compatibility.

Add a new function that read quirk and configuration information from the

The function is adapted from the function dwc3_get_properties() in the
