Hi Dmitry,

This patchset is another attempt at supporting rotary encoders
with stable state on each output states. Previous efforts to
support this has been done by Sascha Hauer [1] and myself [2].

After some discussion we agreed to remove the current ad-hoc
bindings for each of the rotary-encoders types, and instead
introduce "one binding to rule them all".

This patchset introduces a new 'steps-per-period' property.
Such a property can be used to model the three types
of rotary-encoders.

From the GPIO output diagram, we can see where these types

come from, and how the steps-per-period describes each
of them.

              |     |     |     |     |     |     |
  Channel B   |_____|     |_____|     |_____|     |__

                 :  :  :  :  :  :  :  :  :  :  :  :

                |<-------->|
                  one step, steps-per-period = 1

                |<-->|
                  one step, steps-per-period = 2

                |<>|
                  one step, steps-per-period = 4

The 'half-period' property is marked as deprecated and a
warning message is issued if it's used, although the driver
retains its old behavior.

I'm also submitting Ben Gamari's cleanup, with the commit log
slightly ammended.

Feedback welcome!
