This adds nodes for the SerDes devices. They are disabled by default
to prevent any breakage on existing boards.

(no changes since v10)
Changes in v10:
- Move serdes bindings to SoC dtsi
- Add support for all (ethernet) serdes modes
- Refer to "nodes" instead of "bindings"
- Move compatible/reg first
Changes in v4:
- Convert to new bindings
Changes in v3:
- Describe modes in device tree
Changes in v2:
- Use one phy cell for SerDes1, since no lanes can be grouped
- Disable SerDes by default to prevent breaking boards inadvertently.
