[PATCH v5 01/18] tests/functional/arm/test_aspeed_ast2600_sdk: Add USB EHCI test for AST2600 SDK

[Jamin Lin <jamin_lin@aspeedtech.com>]

Add a functional test to verify USB EHCI support on the AST2600
SDK machine 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.
