[PULL 26/32] tests/functional/arm/test_aspeed_ast2600: Add PCIe and network test

["Cédric Le Goater" <clg@redhat.com>]

From: Jamin Lin <jamin_lin@aspeedtech.com>

Extend the AST2600 functional tests with PCIe and network checks.

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
- 81:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

To exercise the PCIe network device, the test adds:

  -device e1000e,netdev=net1,bus=pcie.0
  -netdev user,id=net1

and assigns an IP address to the interface, verifying it with `ip addr`.
