Subject: [PATCH] x86: Use consistent names for region size and conherence id on x86 and ia64.

Use consistent names for region size and conherence id on x86 and ia64.

Signed-off-by: Russ Anderson <rja@....com>

The SGI xp drivers are used on both ia64 and x86.  Using the same
names (sn_coherency_id, sn_region_size) simplies the driver code.
