regulator: cprh-kbss-regulator: update open-loop reference voltages 



Update the CPR open-loop reference voltages for msmcobalt
to ensure that the correct open-loop voltages are calculated
based upon hardware fuse values. In addition, rename Turbo_L2 to
Turbo_L1 as this corresponds to the highest fused corner valid
across all msmcobalt devices.
