Axel Lin d8eb6fa7a9 regulator: st-pwm: Convert to get_voltage_sel
Also remove test for selector in st_pwm_regulator_set_voltage_sel, the checking
is already done in .list_voltage.

Lee Jones 4a5d301328 regulator: Add new driver for ST's PWM controlled voltage regulators
On some STMicroelectronics hardware reside regulators consisting
partly of a PWM input connected to the feedback loop. As the PWM
duty-cycle is varied the output voltage adapts. This driver
allows us to vary the output voltage by adapting the PWM input
duty-cycle.
