ARM: dts: add gbe serdes phy nodes and phandles for netcp dt nodes

This patch adds the serdes phy dt nodes and phandles to access
the same from netcp nodes for the gbe switch. As such the gbe
serdes can be configured during driver initialization.  In other
words, it no longer needs to rely on the serdes configurations
inherited from u-boot. While at it, also remove commented properties
from the DTS.
