sparc64: Probe cpu page size support more portably.
On sun4v, interrogate the machine description. This code is extremely
defensive in nature, and a lot of the checks can probably be removed.
On sun4u things are a lot simpler. There are the page sizes all chips
support, and then Panther adds 32MB and 256MB pages.
Report the probed value in /proc/cpuinfo
