Daniel P. Carvalho bda32d3a74 Documentation/ptp: add the existing implementations.
The page described how to write a lower-half driver but did not say
which ones are in the tree.

- List the two lower-half drivers that register a PTP clock, the dummy
  driver and the Ethernet MAC of the STM32, with the option that
  enables each.
- Say that the clock of the STM32 driver is the PTP counter of the MAC,
  which is also the time base of the timestamps of the received
  packets, and not CLOCK_REALTIME.
- Say that both use the device number 0 by default and so cannot be
  registered at the same time.
