x86/platform/uv: Add UV Hubbed/Hubless Proc FS Files
Indicate to UV user utilities that UV hubless support is available on
this system via the existing /proc infterface. The current interface is
maintained with the addition of new /proc leaves ("hubbed", "hubless",
and "oemid") that contain the specific type of UV arch this one is.
