[PATCH 3/3] regulator: qcom_smd: Avoid overlapping linear voltage ranges

The pm8x41_hfsmps ranges overlap. The first range is from 375000
to 1562500:

 375000 + (95 * 12500) == 1562500

and the second range starts at 1550000. Interestingly, the second
range ends at the correct value when it's set to be the
appropriate start value, 1575000:

 1575000 + ((158 - 96) * 25000) == 3125000
