Subject: [PATCH RFC] regulator: Convert ab8500 to use get_voltage_sel()

This change is required to make ab8500_regulator_get_voltage_sel work.
The regulator core will call set_voltage_time_sel only when get_voltage_sel is
implemented.

Hi,
I don't have this hardware, I'd appreciate if someone can test this patch.
