There are a number of problems with PPS and PTP kconfig options:

1. PPS and PTP_1588_CLOCK depend on EXPERIMENTAL, therefore so must the
   clock drivers.  (And EXPERIMENTAL is deprecated.)
2. PTP_1588_CLOCK depends on PPS, so users or clock driver options must
   explicitly select both.
3. In general, users have to enable too many options to get hardware
   timestamps and PTP working.
4. Boolean options for clock drivers combined with net drivers can force
   the PTP and PPS subsystems to be built-in unnecessarily.

This series changes the options as follows:

1. Nothing depends on EXPERIMENTAL.
2. Only PTP_1588_CLOCK selects PPS.
3, 4. The boolean options are removed and the net driver options select
   PTP_1588_CLOCK.  Where a net driver and associated clock driver are
   separate modules, the clock driver remains optional but is default y.

Looks good, series applied, thanks.
