UPSTREAM: usb: udc: Introduce ->udc_set_speed() method

This patch was copied from kernel commit: 67fdfda4a99ed.

Sometimes, the gadget driver we want to run has max_speed lower than
what the UDC supports. In such situations, UDC might want to make sure
we don't try to connect on speeds not supported by the gadget
driver because that will just fail.

So here introduce a new optional ->udc_set_speed() method which can be
implemented by interested UDC drivers to achieve this purpose.

UPSTREAM: usb: udc-uclass: Fixed problem when no alias is defined in DT

commit 801f1fa442 "dm: usb: udc: Use SEQ_ALIAS to index the USB gadget
ports" changed the way the udevice if found. It uses the alias to find
a udevice for a given USB port number. In the commit log it was stated
that if no alias is provided, the bind order will be used instead. However
it doesn't work. Fixing this by adding a call to uclass_get_device() if
uclass_get_device_by_seq() fails.

UPSTREAM: dm: usb: gadget: Fix boot breakage on sunxi platforms

Fixes commit 013116243950 ("dm: usb: create a new UCLASS ID for USB gadget
devices")

The UCLASS_DRIVER for id UCLASS_USB_GADGET_GENERIC needs to be declared
even for platforms that do not enable DM_USB_GADGET. Otherwise the driver
for their usb peripheral controller fails to bind.

UPSTREAM: dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports

dfu, fastbot and other usb gadget commands take the USB port index as a
parameter. Currently this index is assigned in the order of the driver
bindings.
Changing this behavior using the SEQ_ALIAS feature. This option assign to
the device a SEQ number based on its alias (if it exists)

To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing
naming convention: use "usb" for the name of the gadget UCLASS_DRIVER
(same as for the UCLASS_USB).

If no alias is provided, then the index falls back to the order in which
the bindings took place.

When DM_USB_GADGET the platform code for the USB device must be replaced by

usb_gadget_initialize() probes the USB device driver.
usb_gadget_release() removes the USB device driver.
