Richard Cochran 9c6e0f57b3 ts2phc: Support using a PHC as the master clock.
This patch introduces a new ts2phc source using a PHC device.  There
are multiple use cases for such a master.  By connecting pins of two
or more separate PHC devices together, one may act as the source, and
the others may be synchronized to it in hardware.  In this way, "just
a bunch of devices" together forms a Transparent Clock.  If the master
clock is synchronized to a global time source (like a PPS from a GPS),
then the system becomes a mutli-port Grand Master or a Boundary Clock
with GM capability.
