pwm: Add driver for Amlogic Meson PWM controller
This adds the driver for the PWM controller found in the Amlogic SoCs.
This PWM is only a set of Gates, Dividers and Counters:
PWM output is achieved by calculating a clock that permits calculating
two periods (low and high). The counter then has to be set to switch after
N cycles for the first half period.
The hardware has no "polarity" setting. This driver reverses the period
cycles (the low length is inverted with the high length) for
PWM_POLARITY_INVERSED.
Disabling the PWM stops the output immediately (without waiting for the
current period to complete first).
