Make the dev_get_hwtstamp_phylib function accessible in prevision to use
it from ethtool to read the hwtstamp current configuration.

Change in v8:
- New patch

Change in v10:
- Remove export symbol as ethtool can't be built as a module.
- Move the declaration to net/core/dev.h instead of netdevice.h
