Subject: [PATCH RFT] regulator: da903x: Kill
da903x_[get|set]_[ldo12|ldo14]_voltage_sel() functions
Now the implementation of da903x_set_voltage_sel, da9030_set_ldo14_voltage_sel,
and da9034_set_ldo12_voltage_sel are exactly the same.
da903x_get_voltage_sel, da9030_get_ldo14_voltage_sel and
da9034_get_ldo12_voltage_sel are exactly the same.
So we can use da903x_[get|set]_voltage_sel and kill other functions.

This patch is on top of below patches.
[PATCH RFT 1/2] regulator: da903x: Convert to regulator_list_voltage_linear()
[PATCH RFT 2/2] regulator: da903x: Convert to set_voltage_sel and map_voltage
I should send it as a serial, but I just generate this patch after I sent above 2 patches.
Regards,
Axel
