Subject: [PATCH net-next v10 02/13] net: Move dev_set_hwtstamp_phylib to net/core/dev.h

This declaration was added to the header to be called from ethtool.
ethtool is separated from core for code organization but it is not really
a separate entity, it controls very core things.
As ethtool is an internal stuff it is not wise to have it in netdevice.h.
Move the declaration to net/core/dev.h instead.

Remove the EXPORT_SYMBOL_GPL call as ethtool can not be built as a module.

At this point this function does not need to be defined in a header at
all. But patch 12 will change that.

net/ethtool can be built-in or not, but cannot be built as module, so
no need for the EXPORT_SYMBOL_GPL indeed.
