Subject: [PATCH net-next 2/3] ptp: Make PTP_1588_CLOCK select rather than
 depend on PPS

PTP hardware clock drivers that select PTP_1588_CLOCK must currently
also select PPS.  For those drivers that don't, the user must enable
PPS, then enable PTP_1588_CLOCK, then the driver.  Simplify things for
developers and users by putting this selection in one place.
