ti: netcp: convert to ndo_hwtstamp callbacks

Browse source

Convert TI NetCP driver to use ndo_hwtstamp_get()/ndo_hwtstamp_set()
callbacks. The logic is slightly changed, because I believe the original
logic was not really correct. Config reading part is using the very
first module to get the configuration instead of iterating over all of
them and keep the last one as the configuration is supposed to be identical
for all modules. HW timestamp config set path is now trying to configure
all modules, but in case of error from one module it adds extack
message. This way the configuration will be as synchronized as possible.

There are only 2 modules using netcp core infrastructure, and both use
the very same function to configure HW timestamping, so no actual
difference in behavior is expected.
