[PATCH v1] pps: Increase PPS_MAX_SOURCES value.

[Charlie Johnston]

For consistency with what others use for minors, this
change sets PPS_MAX_SOURCES to MINORMASK.

The PPS_MAX_SOURCES value is currently set to 16. In
some cases this was not sufficient for a system. For
example, a system with multiple (4+) PCIe cards each
with 4 PTP-capable ethernet interfaces could run out
of the available PPS major:minors if each interface
registers a PPS source.
