i915/perf: Find the associated perf-type for a particular device
Since with multiple devices, we may have multiple different perf_pmu
each with their own type, we want to find the right one for the job.
The tests are run with a specific fd, from which we can extract the
appropriate bus-id and find the associated perf-type. The performance
monitoring tools are a little more general and not yet ready to probe
all device or bind to one in particular, so we just assume the default
igfx for the time being.
v2: Extract the bus address from out of sysfs
v3: A new name for a new decade!
