If CONFIG_PHY is not enabled then the dwc3_setup_phy()
returns ENOTSUPP which can be still valid and intentional
so modify error check to handle this -ENOTSUPP.
The same error handling exists in drivers/usb/host/xhci-dwc3.c already
added by commit d648a50c0a ("dwc3: move phy operation to core.c").

Lot of Qualcomm SoC-s use DWC3 controller for both USB2.0 and USB3.0
ports.
Qualcomm has some custom config registers on top of the generic ones,
but for host mode these are not needed.
So lets add the neccessary compatible string.

Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT.
This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use
ofnode as parameter instead of fdt offset. And all the drivers who use
these APIs update to use live dt APIs at the same time.

Add a new function that read quirk and configuration information from the
DT. The goal is to allow platforms using their own version of DWC3 driver
to migrate to the generic DWC3 driver.
The function is adapted from the function dwc3_get_properties() in the
linux dwc3 driver introduced in commit c5ac6116db35d.

Currently the host driver used by dwc3-generic is "xhci-dwc3". This is
a functional driver but it doesn't use the dwc3 core and, in particular,
it lacks some bits that may be important.
For example on the k2 platforms, it is important that the phy are properly
suspended when the USB is not used anymore. The dwc3 core also has a
partial support for quirks.
The new driver can be used as a drop-in replacement for "xhci-dwc3".
In terms of implementation, it may seem strange that 2 private structures
dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this
is simply that the xhci layer expects a struct xhci_ctrl at the beginning
of the private data and it seemed wasteful to include it also for the
peripheral case.
