[PATCH v4 00/22] usb/xhci and usb/msd improvements and tests

[Nicholas Piggin <npiggin@gmail.com>]

This is merged from two series now because code especially the test
cases have started to depend on one another.

The series are "usb/xhci: TR NOOP, TI HCD device, more qtests" from:
https://lore.kernel.org/qemu-devel/20250411080431.207579-1-npiggin@gmail.com/

And "usb/msd: Permit relaxed ordering of IN packets" from:
https://lore.kernel.org/qemu-devel/20250411080431.207579-1-npiggin@gmail.com/

The qtests also depends on the qtest fixes:
https://lore.kernel.org/qemu-devel/20250502030446.88310-1-npiggin@gmail.com/

This series adds better support qtests support for the xhci controller,
adds support for the "TR NOOP" command used by AIX, and adds a new USB
controller model from TI that PowerVM and AIX use.

It also permits relaxed ordering of USB mass-storage
packets from the host, as allowed by the usbmassbulk 1.0 spec, but
not usually seen in drivers. AIX drivers do require this ordering.

Since previous posting the usb/msd series had some changes that Phil
noted. But otherwise the qemu code is mostly unchanged. The qtest code
has had some big changes, cleaned up a lot and started adding some USB
Mass Storage Device tests including one which verifies the relaxed
ordering change. It would be nice if we could plug these into more
comprehensive SCSI tests, but so far it mainly just tests the USB MSD
protocol.
