Add a basic functional test for the AST2700 PCIe Root Complex. The test runs "lspci" to verify that the internal host bridge is enumerated at BDF 0002:00:00.0.
Note: the ASPEED PCIe driver only supports bus 0 with a single device at slot 0, which is reserved for the internal bridge. All endpoint devices must reside on bus 1 to be discovered. As a result, this test only checks that the internal bridge is visible. Attaching pcie-root-port and e1000e devices is not possible without driver changes. This is a temporary solution. See the ASPEED PCIe driver implementation for details: https://github.com/AspeedTech-BMC/linux/blob/aspeed-master-v6.6/drivers/pci/controller/pcie-aspeed.c#L512 Additionally, the ASPEED SDK by default enables only PCIe RC2, so the test covers RC2 only.
