pwm: Support for duty_offset

Support a new abstraction for pwm configuration that allows to specify
the time between start of period and the raising edge of the signal
("duty offset").

This is used in a patch series by Trevor Gamblin for triggering an ADC
conversion and afterwards read out the result. See
