[PATCH net-next v6 12/16] net: Replace hwtstamp_source by timestamping layer

[Kory Maincent <kory.maincent@bootlin.com>]

Replace hwtstamp_source which is only used by the kernel_hwtstamp_config
structure by the more widely use timestamp_layer structure. This is done
to prepare the support of selectable timestamping source.

Signed-off-by: Kory Maincent <kory.maincent@bootlin.com>

Change in v6:
- Follow timestamping layer naming update.
