USB: fixes for v5.6-rc1

DWC3 learned that we can't always depend on Event Status bits. A
problem was solved which would only surface with scatter list on IN
endpoints.

DWC2 got a fix for feature requests (both set and clear) and GetStatus
request.

The serial gadget got a fix for a TX stall bug.

Composite framework now works better for SSP devices.

usb: gadget: serial: fix Tx stall after buffer overflow

Symptom: application opens /dev/ttyGS0 and starts sending (writing) to
it while either USB cable is not connected, or nobody listens on the
other side of the cable. If driver circular buffer overflows before
connection is established, no data will be written to the USB layer
until/unless /dev/ttyGS0 is closed and re-opened again by the
application (the latter besides having no means of being notified about
the event of establishing of the connection.)

Fix: on open and/or connect, kick Tx to flush circular buffer data to
USB layer.

We have TI's glue layer for the Cadence USB3 controller going

Apart from these two big features, we have a bunch of patches switching
over to devm_platform_ioremap_resource() in order to simplify code a
little; and a non-critical fix for DWC3 usage via kexec.
