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 This patch was originally part of a 2-patch series. Patch 2 got applied to the regulator tree as 7c7fac3 "regulator: tps6586x: add support for input supply" without this patch. This broke regulator support on Harmony.
