ARM: dts: msm: specify minimum quotient differences for APC1 CPR on msm8992

Specify the minimum quotient differences for the APC1 CPR
regulator on MSM8992 to ensure that CPR closed-loop operation is
kept enabled even if the target quotient for a higher fuse corner
(say NOM) is less than that of a lower fuse corner (SVS). This
is achieved by setting the target quotient of higher fuse corner
to be the same as that of lower fuse corner.
