The generic EHCI binding does not *require* resets and clocks
properties, and indeed for instance the Allwinner A20 SoCs does not
need or define any resets in its DT.
Don't easily give up if clk_get_bulk() or reset_get_bulk() return an
error, but check if that is due to the DT simply having no entries for
either of them.
This fixes USB operation on all boards with an Allwinner A10 or A20 SoC,
which were reporting an error after commit ba96176ab7:
=======================
Bus usb@1c14000: ehci_generic usb@1c14000: Failed to get resets (err=-2)

When the device tree indicates support for role switching through
the "usb-role-switch" property, take the "role-switch-default-mode"
property into account when deciding which role to put the
controller into.
This makes USB devices work on Apple M1 systems where the device
tree may include a "dr_mode" property that is set to "otg", but
where we need to put the controller into "host" mode to see
devices connected to the type-C ports.

There are a few boards that use hard-coded GPIO definitions in
their respective defconfig files. If the GPIO's are listed
in their device trees, the nop-phy can toggle the GPIO's,
so the EHCI driver does not need to know anything about the
GPIO's. Add functions for getting the phys and remove the GPIO
toggles since the phy will now do that.

The USB_EHCI_OMAP driver currently has a series of Kconfig options
which let users specify a GPIO for the reset pin. Some devices
may have only one reset, while others might have more.
Since there is a nop phy driver, let's selct enable the PHY
system, and imply the nop phy driver. The nop phy driver can now
toggle the reset pins when putting the phy in and out of reset.
If the gpio is listed under the phy, it will get toggled and
the hard-coded config options specifying the GPIO numbers can
eventually go away.

There are devices which cause a USB stall when trying to read strings.
Specifically Arduino Mega R3 stalls when trying to read the product
string.
The stall currently remains unhandled, and subsequent retries submit new
transfers on a stopped endpoint which ultimately cause a crash in
abort_td():
WARN halted endpoint, queueing URB anyway.
XHCI control transfer timed out, aborting...

Linux seems to be able to recover from the stall by issuing a
TRB_RESET_EP command.
Introduce reset_ep() which issues a TRB_RESET_EP followed by setting the
transfer ring dequeue pointer via TRB_SET_DEQ. This allows to properly
recover from a USB stall error and continue communicating with the USB
device.

The imx8mm and imx8mn appear compatible with imx7d-usb
flags in the OTG driver. If the dr_mode is defined as
host or peripheral, the device appears to operate correctly,
however the auto host/peripheral detection results in an error.
The solution isn't just adding checks for imx8mm and imx8mn to
the check for imx7, because the USB clock needs to be running
to read from the USBNC_PHY_STATUS_OFFSET register or it will hang.
Marek requested that I not enable the clocks in ehci_usb_of_to_plat,
so I modified that function to return an unknown state if the
device tree does not explicitly state whether it is a host
or a peripheral.
When the driver probes, it looks to see if it's in the unknown
state, and only then will it read the register to auto-detect.

For whatever reason, usb_setup_ehci_gadget removes and probes USB device
0. However, not all systems have a device 0. Use the first device
instead.
The device probed should probably have something to do with the
controller (as specified by e.g. ums <controller> or fastboot
<controller>). In fact, I find it odd that we probe the USB device in
the first place, because this is just to set up the gadget itself.
Presumably, the controller should be probed by usb_gadget_initialize
somehow.
