The DSCR tests fail on systems that don't have DSCR, so check for the
DSCR in hwcap and skip if it's not present.

This patch adds a test to update the system wide DSCR value repeatedly
and then verifies that any thread on any given CPU on the system must be
able to see the same DSCR value whether its is being read through the
problem state based SPR or the privilege state based SPR.
