regulator: axp20x: AXP717: fix LDO supply rails and off-by-ones

Browse Source 
The X-Powers AXP717 PMIC has separate input supply pins for each group
of LDOs, so they are not all using the same DCDC1 input, as described
currently.

Replace the "supply" member of each LDO description with the respective
group supply name, so that the supply dependencies can be correctly
described in the devicetree.

Also fix two off-by-ones in the regulator macros, after some double
checking the numbers against the datasheet. This uncovered a bug in the
datasheet: add a comment to document this.
