regulator: cpr3-mmss-regulator: update reference voltages for msmcobalt
MSMCOBALT 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 CPR revision 0 vs revisions
1 to 7.
