x86/UV: Set n_lshift based on GAM_GR_CONFIG MMR for UV3
The value of n_lshift for UV is currently set based on the
socket m_val.
For UV3, set the n_lshift value based on the GAM_GR_CONFIG MMR.
This will allow bios to control the n_lshift value independent
of the socket m_val. Then n_lshift can be assigned a fixed value
across a multi-partition system, allowing for a fixed common
global physical address format that is independent of socket
m_val.
Cleanup unneeded macros.
