Note that it's fine if drivers use different terminology for internals.
Many manuals seem to be using the channel terminology and many drivers
use that. But if you prefer devices that's fine with me.

I've applied this with a minor change, see below.

I kept the "st,pwm-num-chan" as property name here to avoid breaking
backwards compatiblity. This series changes it back to "st,pwm-num-chan"
sometime later in this series anyway.
