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.

Set SBE seeprom boot side

The default side for the SBE to boot from is side 0, which
is indicated by a 0 in bit 17 of cfam 0x2808.

When the boot count goes to 1 (the last before giving up), the
start_host logic will switch over to side 1 for the SBE to
boot from.
