To reach higher capacities, arrays of chips are now pretty common.
Unfortunately, most of the controllers have been designed a decade ago
and did not all anticipate the need for several chip-selects. The new
cs-gpios property allows to workaround this limitation by adding as many
GPIO chip-select as needed.

Resending only the binding patch of the series, with the following
changes requested by Rob:
* Fixed the coherency between cs-gpios and gpios-cs
* Added maxItems: 8 (this is a good enough value for most of the cases I
  guess, this can be increased later if needed).
* Adding maxItems: 8 lead to an error when checking the example,
  minItems: 8 had to be added as well to the schema to fix it, not sure
  this was expected or not.
