pwm: meson: generalize 4 inputs clock on meson8 pwm type
Meson8 pwm type always has 4 input clocks. Some inputs may be grounded,
like in the AO domain of some SoCs.
Drop the parent number parameter and make this is constant.
This is also done to make the addition of generic meson8 compatible easier.

dt-bindings: pwm: amlogic: Add a new binding for meson8 pwm types
The binding that is used up to now describe which input the PWM
channel multiplexer should pick among its possible parents,
which are hardcoded in the driver. This isn't a good binding in
the sense that it should describe hardware but not usage.
Add a new binding deprecating the old one that uses clocks in a
better way and how clocks are usually used today: The list of
clocks describe the inputs of the PWM block as they are realised
in hardware.
So deprecate the old bindings and introduce a compatible per SoC
family to replace these.

dt-bindings: pwm: amlogic: fix s4 bindings
s4 has been added to the compatible list while converting the Amlogic PWM
binding documentation from txt to yaml.
However, on the s4, the clock bindings have different meaning compared to
the previous SoCs.
On the previous SoCs the clock bindings used to describe which input the
PWM channel multiplexer should pick among its possible parents.
This is very much tied to the driver implementation, instead of describing
the HW for what it is. When support for the Amlogic PWM was first added,
how to deal with clocks through DT was not as clear as it nowadays.
The Linux driver now ignores this DT setting, but still relies on the
hard-coded list of clock sources.
On the s4, the input multiplexer is gone. The clock bindings actually
describe the clock as it exists, not a setting. The property has a
different meaning, even if it is still 2 clocks and it would pass the check
when support is actually added.
Also the s4 cannot work if the clocks are not provided, so the property is
no longer optional.
Finally, for once it makes sense to see the input as being numbered
somehow. No need to bother with clock-names on the s4 type of PWM.
