Raise the VDD_APC0 and VDD_APC1 CPR floor voltages to be equal to
the Nominal ceiling voltage on CPR revision 0 parts. Also, increase
the number of supported fuse combos to 8, to support up to 8 CPR
revisions using a single speed bin. This ensures stable operation
on some msmcobalt CPR revision 0 parts that cannot operate
reliably with SVS2/SVS voltages and has no impact to CPR rev 1 and
greater parts.
