x86/platform/uv: Add new uv_sysfs platform driver
Add the uv_sysfs driver to construct a read-only sysfs interface at
/sys/firmware/sgi_uv/ to expose information gathered from UV BIOS. This
information includes:
* UV Hub descriptions, including physical location
* Cabling layout between hubs on the fabric
* PCI topology, including physical location of PCI cards
Together, the information provides a robust physical description of a UV
system, useful for correlating to performance data or performing remote
support.
