MediaTek platforms may need the MTU3 controller before U-Boot proper is
available, but the driver is currently selected and built only with the
main U-Boot configuration symbols.
Add an explicit SPL controller option with host and gadget modes. Make
the driver build and its role checks phase-aware so each phase can select
the MTU3 role it needs without coupling it to the U-Boot proper controller
configuration.
The upstream binding locates the xHCI child registers through the parent
ranges property. Select SPL_OF_TRANSLATE for host mode so SPL can resolve
that address before mapping it.

The MTU3 glue driver expects a synthetic mediatek,ssusb child that
combines the device and xHCI register windows. Upstream devicetrees
instead put the device resources on the controller node and describe the
xHCI window with a standard child node, so U-Boot cannot use an upstream
topology.
Switch to the upstream layout. The controller owns the shared resources
and the device MAC, with the device register offsets relative to it as in
Linux. The gadget role binds as a node-less internal device, while the
host role binds to an enabled xHCI child and uses its own clocks,
supplies and register window. dr_mode selects the role and defaults to
otg, and the Kconfig choice constrains which role the build provides.
The legacy child layout is rejected explicitly so its combined register
window cannot be mistaken for the device MAC.
Convert the in-tree MT8183 and MT8512 devicetrees in the same commit so
neither platform is left without USB. MT8512 stays peripheral-only
because its xHCI host interrupt is not documented and the
mediatek,mtk-xhci binding requires it.

Fastboot unregisters the USB gadget from the completion callback of
its final OKAY response. MTU3 QMU can report that request complete
while bytes remain in the endpoint TX FIFO. Disabling the USB function
immediately can therefore disconnect the host before it receives the
response.
Before selecting the high-speed or SuperSpeed disconnect operation, poll
the FIFO state of enabled IN endpoints that have no pending requests.
Bound the wait to 1 ms. If a FIFO does not drain, reset its endpoint,
force the disconnect, and propagate -ETIMEDOUT through the gadget pullup
operation. Endpoints with pending requests are skipped so an ordinary
disconnect does not wait for an active transfer.

Implement .handle_interrupts callback as a replacement for deprecated
dm_usb_gadget_handle_interrupts() function. The new callback allows
for each DM capable USB gadget controller driver to define its own
IRQ handling implementation without colliding with other controller
drivers.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

When allocate the GPD ring, and tell its address to the controller, then
the driver starts or resumes the QMU, the controller will try to access
the first GPD, so need flush the first one to avoid wrong GPD status.

As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:
- Ensuring that all host controller options (other than the very legacy
old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and
OF_CONTROL.
- Remove other parts of Kconfig logic that had platforms pick DM_USB.
- To keep Kconfig happy, have some select statements test for USB_HOST
as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
host or gadget roles. For the various HCD options that have platform
glue options, group them together and update dependencies in some
cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
it, disable it.

will try to access the next GPD after processing the current one,
if not flush the next GPD, the controller may get wrong GPD status.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
