Subject: [PATCH 30/73] regulator: ab8500: Remove Vsafe voltage settings

From: Bengt Jonsson <bengt.g.jonsson@...ricsson.com>

The Vsafe regulator should not be handled by the kernel, it
should be setup before the kernel starts. This patch removes
the voltage settings.

Current consumption will increase slightly (rough estimate 25
uA) when the platform is in the low power state because SoC
sets a voltage of 0.95 V where the kernel set a voltage of
0.925 V.
