x86/platform/uv: Setup UV functions for Hubless UV Systems

Add more support for UV systems that do not contain a UV Hub (AKA
"hubless").  This update adds support for additional functions required:

    Use PCH NMI handler instead of a UV Hub NMI handler.

    Initialize the UV BIOS callback interface used to support specific
    UV functions.
