ptp: Enable clock drivers along with associated net/PHY drivers
Where a PTP clock driver is associated with a net or PHY driver, it should be enabled automatically whenever that driver is enabled. Therefore: - Make PTP clock drivers select rather than depending on PTP_1588_CLOCK - Remove separate boolean options for PTP clock drivers that are built as part of net driver modules. (This also fixes cases where the PTP subsystem is wrongly forced to be built-in.) - Set 'default y' for PTP clock drivers that depend on specific net drivers but are built separately Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
