ac28e59a57 usb: Migrate to support live DT for some driver
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.

d624434f5e dwc3-generic: Don't fail probe if clk/reset entries are absent
Some boards don't populate clk/reset entries as these are are optional
as per binding documentation. Therefore, don't fail driver probe if
clk/reset entries are absent in DT.

This fixes fastboot failures seen due to enabling of CONFIG_CLK on AM57xx

ba6c5f7a28 usb: dwc3: Add dwc3_of_parse() to get quirks information from DT
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.

b575e90916 usb: dwc3-generic: add a new host driver that uses the dwc3 core
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.
