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.
