We're renaming the 'st,pwm-num-chan' binding to 'st,pwm-num-devs' to
be more inline with the naming conventions of the subsystem.  Where
we used to treat each line as a channel, the PWM convention is to
describe them as devices.

The second documentation adaption entails adding support for PWM
capture devices.  A new clock is required as well as an IRQ line.
We're also adding a new property similar to the one described
above, but for capture channels.  Typically, there will be less
capture channels than PWM-out, since all channels have the latter
capability, but only some have capture support.
