[PATCH v3 17/17] tests/functional/aarch64/test_aspeed_ast2700: Add USB EHCI test for AST2700 A1/A2

[Jamin Lin <jamin_lin@aspeedtech.com>]

Add a functional test to verify USB EHCI support on the AST2700 A2/A1
by attaching a USB keyboard device and checking its
enumeration via lsusb.

This introduces a helper routine that runs lsusb in the guest
and validates that the emulated "QEMU USB Keyboard" is detected.
