Subject: [5/5] pch_gbe, ptp_pch: Fix the dependency direction between these
drivers
commit 18d359ceb04485df0e387e04b0e52a761c4c58a0 upstream.
In commit a24006ed12616bde1bbdb26868495906a212d8dc ('ptp: Enable clock
drivers along with associated net/PHY drivers') I wrongly made
PTP_1588_CLOCK_PCH depend on PCH_GBE. The dependency is really the
other way around. Therefore make PCH_GBE select PTP_1588_CLOCK_PCH
and remove the 'default y' from the latter.

Subject: [1/5] pps, ptp: Remove dependencies on EXPERIMENTAL
commit c56283034ce28f99de494b69896528ae90cd9730 upstream.
These are now established subsystems, and we want drivers to be able
to select PPS and PTP_1588_CLOCK without depending on EXPERIMENTAL.
Further, the use of EXPERIMENTAL is now deprecated in general.

Subject: [3/5] ptp: Enable clock drivers along with associated net/PHY
drivers
commit a24006ed12616bde1bbdb26868495906a212d8dc upstream.
Where a PTP clock driver is associated with a net or PHY driver, it
should be enabled automatically whenever that driver is enabled.
Therefore:
- Make PTP clock drivers select rather than depending on PTP_1588_CLOCK
- Remove separate boolean options for PTP clock drivers that are built
as part of net driver modules. (This also fixes cases where the PTP
subsystem is wrongly forced to be built-in.)
- Set 'default y' for PTP clock drivers that depend on specific net
drivers but are built separately

Subject: [2/5] ptp: Make PTP_1588_CLOCK select rather than depend on PPS
commit 42a7ccef0a06519e2ea0be71d7c0f4ed9198509f upstream.
PTP hardware clock drivers that select PTP_1588_CLOCK must currently
also select PPS. For those drivers that don't, the user must enable
PPS, then enable PTP_1588_CLOCK, then the driver. Simplify things for
developers and users by putting this selection in one place.
