[PATCH v2 4/5] arm64: dts: ls208xa: describe the Lynx 10G SerDes blocks

From: Vladimir Oltean <vladimir.oltean at nxp.com>

Describe the two Lynx 10G SerDes blocks and their associated lanes found
on the LS208xA SoC. The nodes are left disabled at the SoC level; board
DTs will enable them once there are consumers.
