This series adds few updates to RISC-V ACPI namespace for virt platform. Additionally, it has patches to enable ACPI table testing for RISC-V.
1) PCI Link devices need to be created outside the scope of the PCI root complex to ensure correct probe ordering by the OS. This matches the example given in ACPI spec as well. 2) Add PLIC and APLIC as platform devices as well to ensure probing order as per BRS spec [1] requirement. 3) BRS spec requires RISC-V to use new ACPI ID for the generic UART. So, update the HID of the UART. 4) Enabled ACPI tables tests for RISC-V which were originally part of [2] but couldn't get merged due to updates required in the expected AML files. I think combining those patches with this series makes it easier to merge since expected AML files are updated.

Changes since v2: 1) Updated commit message with exact requirement in the BRS. 2) Addressed Igor's comments. 3) Rebased and updated tags. Changes since v1: 1) Made changes in gpex-acpi.c generic as per feedback from Michael. This changes the DSDT for aarch64/virt and microvm machines. Hence, few patches are added to update the expected DSDT files for those machine so that CI tests don't fail. 2) Added patches to enable ACPI tables tests for RISC-V including a patch to remove the fallback path to search for expected AML files. 3) Rebased and added tags.
