[PATCH v2 5/8] tests/functional/aarch64/test_aspeed_ast2700: Enable PCIe2 DTS status for AST2700 tests

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

PCIe2 is disabled by default starting from SDK v10.00.

Add a helper function to stop U-Boot autoboot and update the device
tree at runtime, setting the PCIe2 node status to "okay" before
booting Linux. This allows the AST2700 functional test to verify
the PCIe2 root complex behavior correctly.
