Simplified Precision Time Measurement driver, activates PTM feature
if a PCIe PTM requester (as per PCI Express 3.1 Base Specification

The driver does not take part in facilitating PTM conversations,
neither does it provide any useful services, it is only responsible
for setting up the required configuration space bits.
As of writing, there aren't any PTM capable devices on the market
yet, but it is supported by the Intel Apollo Lake platform.
Can you also add lspci support for the PTM capability? That will help
debugging.

Do I also send it to this list? Or directly to Martin?
As for the kernel code side, still cleaning things up.
