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)
+ IMAXled = 160000 * (592 / 600.5) * (1 / max-current-switch-number)
And the minimum output current formula:
- IMINled = 3300 * (592 / 600.5) * (1 / display-rows)
+ IMINled = 3300 * (592 / 600.5) * (1 / max-current-switch-number)
+ where max-current-switch-number is determinated by led configuration
+ and depends on how leds are physically connected to the led driver.
