This patch adds support to this driver for "brcm,bcm63268-switch".
However, less I am mistaken, this support doesn't work without
patches 3/4 and 4/4 of this series.

I think it would be better to re-range this series so
that support for "brcm,bcm63268-switch" works when it is
added to/enabled in the driver.
