regulator: cpr3-hmss-regulator: set reference voltage based on fuse values

For parts with SoC revision 3, it is necessary to set the Turbo
open-loop reference voltage based upon fuse values.

Update the cpr3-hmss-regulator driver to use the following logic:

if (speedbin==1 && cpr_rev>=5)
    turbo_ref_volt = 1.04 V
else
    turbo_ref_volt = 1.14 V
