The Svpbmt extension provides specification of "Page-Based Memory
Types", or memory attributes (e.g. cacheability constraints).
Extend the pmap code to apply memory attributes when creating/updating
PTEs. This is done in a way which has no effect on CPUs lacking Svpbmt
support, and is non-hostile to alternate encodings of memory attributes
-- a future change will enable this for T-HEAD CPUs, which implement
this PTE feature in an different (incompatible) way.
