pwm: sun4i: Add support for H6 PWM
Now that sun4i PWM driver supports deasserting reset line and enabling bus clock, support for H6 PWM can be added. Note that while H6 PWM has two channels, only first one is wired to output pin. Second channel is used as a clock source to companion AC200 chip which is bundled into same package.
