msm: cpr-regulator: modify the dts definition for cond-min-volt

Previously, cpr-cond-min-volt-fuse defined the fuse row number and the
value used to compare with the whole row efuse value. The cpr-regulator
driver would then conditionally apply a higher CPR floor voltage for all
voltage corners if the efuse value differed from the expected value.

However, only a subset of the bits in the efuse are used for the
cond-min-volt feature. If any of the other bits in the fuse are set, then
the cpr-regulator driver incorrectly applies the higher floor voltage even
if the cond-min-volt bits are set correctly.

Modify the cpr-regulator driver and the cpr-regulator device tree
properties so that only specific bits in the fuse are compared to the
expected value. If the value of the cond-min-volt bits in the fuse is
not equal to the value defined in device tree, then set the MIN_VOLTAGE
flag.
