Conrad Meyer aa71f18e47 NTB: Flesh out the rest of the xeon_setup_b2b_mw changes
Move all Xeon secondary register setup to the setup_b2b_mw routine.  We
use subroutines to make it a bit less wordy than the Linux version.

Adds a new tunable, 'hw.ntb.b2b_mw_share'.  By default, it is off
(zero).  If both sides enable it (any non-zero value), the NTB driver
attempts to use only half of a memory window for remote register MMIO
access.

This is still part of the large Linux rewrite (e26a5843).
