net: Introduce a new MII time stamping interface.
Currently the stack supports time stamping in PHY devices. However,
there are newer, non-PHY devices that can snoop an MII bus and provide
time stamps. In order to support such devices, this patch introduces
a new interface to be used by both PHY and non-PHY devices.
In addition, the one and only user of the old PHY time stamping API is
converted to the new interface.
