[PATCH v3 12/12] tests/functional/arm/test_aspeed_ast1030: Test the usbredir server transport

[Jamin Lin <jamin_lin@aspeedtech.com>]

Export the AST1030 UDC gadget with x-usb-redir-server and import it on an
AST2600 with usb-redir, then check that the AST2600 enumerates it. That
covers the announce, control and enumeration paths of the transport, and
the UDC model behind it.

The two machines have to come from the same QEMU binary, because a
functional test gets only one. ast1030-evb and ast2600-evb are both in
qemu-system-arm.
