Allwinner H616 PWM block is quite different from the A10 or H6, but at
the end, it uses the same clocks as the H6; so the sun4i pwm binding can
be used.
It has 6 channels than can generate PWM waveforms.
If the bypass is enabled (one bypass per channel) the output is no more
a PWM waveform, but a clock that can (and is) used as input for other
devices, like the AC300 PHY.
