pwm: Update DT bindings to reference pwm.txt for cells documentation
...
The PWM client cells format is documented in the generic pwm.txt
documentation and duplicated in all PWM driver bindings. Remove
duplicate information and reference pwm.txt instead.

pwm: dt: Fix description of second PWM cell
...
The second cell in the PWM specifier denotes the period in nanoseconds,
not the duty cycle. The latter can be freely configured at runtime and
a PWM with a fixed duty cycle would be rather pointless.

pwm: i.MX: add devicetree support
...
At the same time remove platform based support. No user for
this driver has made it into mainline so far, so all we break
is out of tree stuff.
