[PATCH v2 13/14] tests/functional/arm/test_aspeed_ast2600: add PCIe enumeration test

[Jamin Lin via <qemu-arm@nongnu.org>]

Extend the AST2600 functional tests with a PCIe enumeration check.

This patch introduces a new helper "do_ast2600_pcie_test()" that runs
"lspci" on the emulated system and verifies the presence of the expected
PCIe devices:

- 80:00.0 Host bridge: ASPEED Technology, Inc. Device 2600
- 80:08.0 PCI bridge: ASPEED Technology, Inc. AST1150 PCI-to-PCI Bridge
