regulator: ab8500: Remove Vsafe voltage settings
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.
