Since there are no current users of the property, the property doesn't directly reflect the hardware and the default value (2) is known to work on multiple boards, remove the code handling this property and instead always configure the hardware according to the known to work default. This property can be properly introduced in the binding in the future if it really turns out that different boards need different configurations. Signed-off-by: Nícolas F. R. A.
