For consistency with what ptp uses for minors, this change sets PPS_MAX_SOURCES to MINORMASK + 1.
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.
Note: Alternate approach for #118
Testing:
Ran checkpatch.pl, no issues.
Built locally and confirmed it built without errors.
