Enable the Annex F Time Sync explicitly for DRA7x and AM4372.
With this enabled the L2 PTP is working.

while at that rename TS_BIT8 to TS_TTL_NONZERO

L2 works fine without this bit. If this is needed for V3 hardware,
then it should have its own code variant.

Is this bit finally documented for am335x?

Thanks,
