This patch series adds some fixes for ARM virt machine pxb support.
1. Pass addr offset for IO, MMIO and bus number when builing crs, because
the addr_trans is needed to describe an addr resource. [1]
2. Inform guest os not to ignore the resource map generated by firmware as
the x86 default way. [2]
3. Enable pxb for ARM virt machine by default.
4. Update expected DSDT files with the above changes and enable the pxb
unit-test.

v4->v5:
* Modify commit logs of patch [2/8] and [8/8] which confuse git-am.

v3->v4:
* Separate the patch of ordering root buses for further discussion. [3]

v2->v3:
* Reorder the root bridges.
* Exclude resources of extra root bridges from main root bridge's _CRS.

v1->v2:
* Update expected DSDT files.
* Quote PCI Firmware spec as comments.
