[ Upstream commit 122e951eb8045338089b086c8bd9b0b9afb04a92 ]

Currently set MP5496 Buck and LDO ranges dont match its datasheet[1].
According to the datasheet:
Buck range is 0.6-2.1875V with a 12.5mV step
LDO range is 0.8-3.975V with a 25mV step.

So, correct the ranges according to the datasheet[1].
