net: ethernet: ravb: Add gPTP support for Gen4
While driver advertises gPTP support on Gen4 platforms it is in fact
completely broken. On R-Car Gen4 devices the RAVB module have no
internal gPTP clock as generations before it. Instead it utilizes a
system-wide gPTP clock.
This change utilizes the refactoring of the RAVB gPTP code to add
support for a system-wide clock and stops the Gen4 devices trying to use
the non-existing internal gPTP clock.
To remain backward compatible the ptp-timer property is optional.If not
present, or not enabled, the RAVB driver will no longer advertise gPTP
support to user-space.
