+ Adds support to dynamically detect the presence of the SVPBMT
+ ISA-extension (Supervisor-mode: page-based memory types) and
+ enable its usage.

+ that indicate the cacheability, idempotency, and ordering
+ properties for access to that page.
The SVPBMT extension is only available on 64Bit cpus.
