net: Convert PHYs hwtstamp callback to use kernel_hwtstamp_config
The PHYs hwtstamp callback are still getting the timestamp config from
ifreq and using copy_from/to_user.
Get rid of these functions by using timestamp configuration in parameter.
This also allow to move on to kernel_hwtstamp_config and be similar to
net devices using the new ndo_hwstamp_get/set.
This adds the possibility to manipulate the timestamp configuration
from the kernel which was not possible with the copy_from/to_user.
