regulator: cprh-kbss-regulator: support per-rev fuse reference voltages

Add support for per-chip revision open-loop fuse reference
voltages. This allows for the correct calculation of open-loop
voltages across msmcobalt chip revisions where the fused
reference voltages vary. Lastly, update the compatible string for
existing msmcobalt v1 CPR APC devices.
