Subject: [PATCH 1/2] ARM: dts: dra7: Increase max-voltage of pbias regulator

From: Ravikumar Kattekola <rk@...com>

As per recent TRM, PBIAS cell on dra7 devices supports
3.3v and not 3.0v as documented earlier.

Update PBIAS regulator max voltage to match this.

Document reference:
SPRUI30C – DRA75x, DRA74x Technical reference manual- November 2016

Tested on:
DRA75x PG 2.0 REV H EVM
