Resetting an XHCI controller inside xhci_register undoes any register
setup performed by the platform driver. And at least on the Allwinner
H6, resetting the XHCI controller also resets the PHY, which prevents
the controller from working. That means the controller must be taken out
of reset before initializing the PHY, which must be done before calling
xhci_register.
The logic in the XHCI core was added to support the Raspberry Pi 4
(although this was not mentioned in the commit log!), which uses the
xhci-pci platform driver. Move the reset logic to the platform driver,
where it belongs, and where it cannot interfere with other platform
drivers.
This also fixes a failure to call reset_free if xhci_register failed.

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.

The ST-Ericsson DB8500 SoC contains a MUSB OTG controller which

nothing special about it - add a simple glue driver for Ux500

There are no SoC-specific registers etc needed to make USB work.
The new Ux500 glue driver is only tested to work with DM_USB

All newer Allwinner SoCs (since about 2013) miss the CONFIGDATA register
in their MUSB implementation, so they need a quirk to hardcode this.
Currently this quirk depends on listing the SoCs affected in musb_reg.h,
which means that this list needs to grow with every new chip.
Move the quirk feature into Kconfig, next to PIO_ONLY, and change the
default to y (for Allwinner builds), while listing the early
implementations as exceptions.
This fixes USB peripheral operation on some newer SoCs, which were not
explicitly listed before.

According to EHCI spec, software needs to do handshake with HC for
safely removing QH from async list. This handshake is implemented by
setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD
register and poll the IAA (Interrupt on Async Advance bit) in the
USB_USBSTS to ensure the HC has released all on-chip state that may
potentially reference one of the data structures just removed.
Current codes only check active status of the last QTD, but this can't
ensure the QH is released from HC. We can meet unrecoverable
"EHCI timed out on TD" errors when running UEFI SCT tests on USB disk.
The USB_ASYNCLISTADDR register is changed to a invalid address when the
issue happens. It is fixed after adding the IAA handshake.
Steps to reproduce the issue:
1. Build the UEFI SCT from https://github.com/tianocore/edk2-test
2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2
3. Copy SCT files and Shell.efi to USB disk FAT partition
4. Load the Shell.efi from USB FAT, and run bootefi to execute it
5. After booting into Shell, enter the SCT directory and run "sct -a"
to execute all tests.
6. Tests run about 1 hour and stop with many EHCI timeout errors like

If musb_peri_rx_ep() was called to process received HW buffer but U-Boot
cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt
was marked as processed also when HW buffer stayed unprocessed.
U-Boot tried to process this buffer again when it received interrupt again,
but it can receive it only when sender (host) sends a new data. As sender
(host) is not going to send a new data until U-Boot process current data
this issue caused a deadlock in case sender (host) is emitting data faster
than U-Boot can process it.
Reading musb intrrx register automatically clears this register and marks
interrupt as processed. So to prevent marking interrupt in U-Boot as
processed, adds a new variable pending_intrrx which would contain
unprocessed bits of intrrx register.
For a second step, every time when musb_peri_rx_ep() is called and there
are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either
acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was
processed or set corresponding bit in pending_intrrx that HW buffer was not
fully processed yet and next iteration is required after U-Boot allocates
space for reading HW buffer.
