TX timestamps are sent by SJA1110 as Ethernet packets containing
metadata, so they are received by the tagging driver but must be
processed by the switch driver - the one that is stateful since it
keeps the TX timestamp queue.
This means that there is an sja1110_process_meta_tstamp() symbol
exported by the switch driver which is called by the tagging driver.
There is a shim definition for that function when the switch driver is
not compiled, which does nothing, but that shim is not effective when
the tagging protocol driver is built-in and the switch driver is a
module, because built-in code cannot call symbols exported by modules.
So add an optional dependency between the tagger and the switch driver,
if PTP support is enabled in the switch driver. If PTP is not enabled,
sja1110_process_meta_tstamp() will translate into the shim "do nothing
with these meta frames" function.
