Add Qualcomm's PFT v1.1 peripheral ID to supported devices.
This device could be found at least in MSM8974 and APQ8064
chipsets.

I'm essentially good with that. On the flip side "PFT" is the format
of the output generated by the tracer. What is important to identify
is the type of tracer fitted to the SoC, either "ETM" or "PTM".

I was unable to find PTM 1.1 in the ARM documentation and PFT
v1.1 is supported only by PTM, if understand it correctly.

It does not change anything - PFT is the protocol and PTM is the tracer.
