net: macvlan: convert to ndo_hwtstamp_get() / ndo_hwtstamp_set()
macvlan is one of the stackable net devices which pass the hardware timestamping ops to the real device through ndo_eth_ioctl(). This prevents converting any device driver to the new hwtimestamping API without regressions. Remove that limitation in macvlan by using the newly introduced helpers for timestamping through lower devices, that handle both the new and the old driver API. macvlan only implements ndo_eth_ioctl() for these 2 operations, so delete that method.
