This adds appropriate descriptions for the macs which use the SerDes. The
156.25MHz fixed clock is a crystal. The 100MHz clocks (there are
actually 3) come from a Renesas 6V49205B at address 69 on i2c0. There is
no driver for this device (and as far as I know all you can do with the
100MHz clocks is gate them), so I have chosen to model it as a single
fixed clock.
Note: the SerDes1 lane numbering for the LS1046A is *reversed*.
This means that Lane A (what the driver thinks is lane 0) uses pins
SD1_TX3_P/N.

Changes in v10:
- Move serdes descriptions to SoC dtsi
- Don't use /clocks
- Use "descriptions" instead of "bindings"
- Split off defconfig change into separate patch
Changes in v9:
- Fix name of phy mode node
- phy-type -> fsl,phy
Changes in v8:
- Rename serdes phy handles to use _A, _B, etc. instead of _0, _1, etc.
This should help remind readers that the numbering corresponds to the
physical layout of the registers, and not the lane (pin) number.
Changes in v6:
- XGI.9 -> XFI.9
Changes in v4:
- Convert to new bindings
