This adds appropriate bindings 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.
