Add support for the proper dwc3 device tree binding support as specified
in the offical device tree spec.
Initially, add support for the LS1028A support. Other SoCs should be
easy to add by just adding the corresponding compatible string.
Unfortunately, the device trees of all other layerscape SoCs are not
converted and uses a wrong compatible string only known in u-boot.
To maintain backwards compatibility with current u-boot device trees,
add the generic "fsl,layerscape-dwc3" compatible string.
OTG mode is not supported yet. The dr_mode in the devicetree will either
have to be set to peripheral or host.

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.
Some files did not contain any GPIO code at all, so this header was
completely unused.
A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.
The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

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.

There are no SoC-specific registers etc needed to make USB work.

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.
