regulator: cpr3-regulator: adjust voltage limits based upon aging results

Adjust the floor, ceiling, and open-loop voltages for each corner
of each CPR3 regulator based upon aging measurements.  This
allows the fixed open-loop voltage adjustment to be reduced since
it no longer has to account for the maximum possible aging
adjustment.  This in turn leads to more situations where LDO mode
may be used for the HMSS CPR3 regulators since the LDO must
always operate at the open-loop voltage.
