Subject: [PATCH RESEND] ARM: tegra: harmony: add regulator supply name and its input supply

Name the regulator as per board schematics and adds its
supply name info in regulator data.
Add the always on fixed regulator to refer the battery supply.

Use this fixed regulator for input supply of some of PMIC
regulator

[PATCH 0/2] regulator: tps6586x: support for input supply

There is change in the regulator driver of tps6586x to support input
supply, this change is also require to avoid any functionality break.
The regulator change is in the Mark's regulator/for-next, this change
should also go from this tree.
Resending this as Mark suggested.
