zephyr: shim: set a placeholder period cell for pwms property

Update all pwms entries to set a period property. This is part of an
ongoing standardization effort in the PWM subsystem in Zephyr, for the
moment just set a "0" placeholder (it's not used by any high level
driver), will followup setting it to the target value once we'll have
the frequency dt macro available, and then use them in the higher level
driver and deprecate the old frequency label properties on a later
stage.
