Subject: [RFT][PATCH] regulator: ab8500: Remove get_voltage_sel for fixed
 voltage

Current code sets get_voltage_sel to ab8500_regulator_get_voltage_sel,
however both ab8500_regulator_mode_ops and ab8500_regulator_ops do not
have voltage_bank, voltage_reg and voltage_mask settings.
So it looks wrong to use ab8500_regulator_get_voltage_sel as
get_voltage_sel callback in these cases.

A simple fix is just not implement get_voltage_sel, regulator core will
report microvolts in sysfs even with only list_voltage().

Just found this needs to be fixed after I sent previous ab8500 patches,
this patch is on top of previous ab8500 fixes.
