regulator: cpr3-mmss-regulator: update reference voltages for msmcobalt v2

Browse source 
MSMCOBALT v2 parts with CPR fusing revision 1 and above will have
their open-loop voltage fuses blown assuming new lower reference
voltages.  These lower reference values allow for fusing parts
with lower open-loop voltages than was possible before.  Update
the driver in order to use a different set of open-loop fuse
reference voltages for MSMCOBALT v2 CPR revision 0 vs revisions
1 to 7.
