Martin Blumenstingl d8f22636a4 regulator: pwm-regulator: Add validity checks in continuous .get_voltage
[ Upstream commit c92688cac239794e4a1d976afa5203a4d3a2ac0e ]

Continuous regulators can be configured to operate only in a certain
duty cycle range (for example from 0..91%). Add a check to error out if
the duty cycle translates to an unsupported (or out of range) voltage.
