Don't run vcs workaround on non-dd10 chips
The VCS workaround is only required (and only make sense)
on P9 DD1.0 based systems. This code does a check of the
chip level and does not run the workaround if the chip
is not DD1.0.
The code will continue to run some of the other workarounds
because although not required for non-dd10 chips, they
do no harm.
Resolves openbmc/openbmc#1695
