USB: add RESET_RESUME quirk for NVIDIA Jetson devices in RCM

NVIDIA Jetson devices in Force Recovery mode (RCM) do not support
suspending, ie. flashing fails if the device has been suspended. The
devices are still visible in lsusb and seem to work otherwise, making
the issue hard to debug. This has been discovered in various forum
posts, eg. [1].

The patch has been tested on NVIDIA Jetson AGX Xavier, but I'm adding
all the Jetson models listed in [2] on the assumption that they all
behave similarly.
