Some of the SN code & #defines related to compact nodes & IO discovery
have gotten stale over the years. This patch attempts to clean them up.
Some of the various SN MAX_xxx #defines were also unclear & misused.

The primary changes are:

	- use MAX_NUMNODES. This is the generic linux #define for the number
	  of nodes that are known to the generic kernel. Arrays & loops
	  for constructs that are 1:1 with linux-defined nodes should
	  use the linux #define - not an SN equivalent.

	- use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the
	  number of nodes in the SSI system. Compact nodes are a hack to
	  get around the IA64 architectural limit of 256 nodes. Large SGI
	  systems have more than 256 nodes. When we upgrade to ACPI3.0,
	  I _hope_ that all nodes will be real nodes that are known to
	  the generic kernel. That will allow us to delete the notion
	  of "compact nodes".

	- add MAX_NUMALINK_NODES for the total number of nodes that
	  are in the numalink domain - all partitions.

	- simplified (understandable) scan_for_ionodes()

	- small amount of cleanup related to cnodes

1) workaround a h/w reset issue
2) to improve the determination of FPGA-based h/w in
   the arch/ia64/sn/kernel/tiocx code.

This patch fixes an ordering issue between the init code for the
tiocx bus driver and tiocx-related device drivers.   Also adds
a new brick to the list of known FPGA bricks.

Here is a patch to enable the SGI tiocx bus driver to distingush between
FPGA-attached h/w and non-FPGA-attached h/w.

Hi Tony,

This patch against ia64-test-2.6.12 fixes a bug where the tiocx code
was inadvertently un-doing some address modifications done in earlier
fixup code.    This patch just removes the offending code.
