[PATCH 04/10] arch/x86/platform/uv: BAU replace uv_physnodeaddr

[Andrew Banman <abanman@sgi.com>]

The BAU driver should use the functions provided by uv_hub.h rather than
its own implementations. uv_physnodeaddr converts vaddrs to paddrs for
BAU MMR fields, but this is done better by uv_gpa_to_offset.
