2013-04-03regulator: ab8500: Add mode operation for v-amicLee Jones1-32/+161
v-amic1 and v-amic2 regulators have dedicated mode registers and share the same mode bit. This patch adds special handling for those regulators. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

In former functions, only can set Vaux3 to 2.91V, because the highest bit of Vaux3 register is put into another register. So add new expanded functions for Vaux3's operation.

However, they have min_uV setting with n_voltages = 1, so use regulator_list_voltage_linear instead. Also remove setting set_voltage_time_sel for ab8500_regulator_mode_ops. It is used only for fixed voltage, so it does not need to implement set_voltage_time_sel.
