sparc64: Add support for ADI register fields, ASIs and traps

SPARC M7 processor adds new control register fields, ASIs and a new
trap to support the ADI (Application Data Integrity) feature. This
patch adds definitions for these register fields, ASIs and a handler
for the new precise memory corruption detected trap.

This is a backport of patch sent upstream and brings UEK code in sync
with upstream patch v6.
