From: George Stark <gnstark@salutedevices.com>

Get rid of the property "awinic,display-rows" and calculate it
in the driver using led definition nodes.

           The maximum output current of each LED is calculated by the
           following formula:
-            IMAXled = 160000 * (592 / 600.5) * (1 / display-rows)
