regulator: cpr3-mmss-regulator: add support for msmcobalt v2 fuses

MSMCOBALT v2 uses different open-loop fuse reference voltages
than MSMCOBALT v1.  Update the cpr3-mmss-regulator driver so that
it uses the proper set of reference voltages for v1 and v2.  Also
change the compatible string of existing MSMCOBALT
cpr3-mmss-regulator devices to be for v1 explicitly so that the
v2 reference voltages are not erroneously used on v1 boards.
