Subject: [PATCH 2/3] [v2] powerpc: fsl: update fman dt binding for PCS PHY

From: Shaohui Xie <Shaohui.Xie@...escale.com>

PCS PHY can support backplane (1000BASE-KX and 10GBASE-KR), this needs
to change corresponding serdes lane settings, so a reference is needed
for serdes lane. This patch describes properties needed for PCS PHY to
support backplane.
