Nicolas Pitre d1cbfd771c ptp_clock: Allow for it to be optional
In order to break the hard dependency between the PTP clock subsystem and
ethernet drivers capable of being clock providers, this patch provides
simple PTP stub functions to allow linkage of those drivers into the
kernel even when the PTP subsystem is configured out. Drivers must be
ready to accept NULL from ptp_clock_register() in that case.

And to make it possible for PTP to be configured out, the select statement
in those driver's Kconfig menu entries is converted to the new "imply"
statement. This way the PTP subsystem may have Kconfig dependencies of
its own, such as POSIX_TIMERS, without having to make those ethernet
drivers unavailable if POSIX timers are cconfigured out. And when support
for POSIX timers is selected again then the default config option for PTP
clock support will automatically be adjusted accordingly.

The pch_gbe driver is a bit special as it relies on extra code in
drivers/ptp/ptp_pch.c. Therefore we let the make process descend into
drivers/ptp/ even if PTP_1588_CLOCK is unselected.

If you have a network (Ethernet) card belonging to this class, say Y.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about Intel cards. If you say Y, you will be asked for
your specific card in the following questions.

---help---
This driver supports Intel(R) PRO/100 family of adapters.
To verify that your adapter is supported, find the board ID number
on the adapter. Look for a label that has a barcode and a number
in the format 123456-001 (six digits hyphen three digits).
Use the above information and the Adapter & Driver ID Guide that
can be located at:
<http://support.intel.com>
to identify the adapter.
