drm/i915/perf: Add 'render basic' Gen8+ OA unit configs

Adds a static OA unit, MUX, B Counter + Flex EU configurations for basic
render metrics on Broadwell, Cherryview, Skylake and Broxton. These are
auto generated from an XML description of metric sets, currently
maintained in gputop, ref:

 https://github.com/rib/gputop
 > gputop-data/oa-*.xml
 > scripts/i915-perf-kernelgen.py

 $ make -C gputop-data -f Makefile.xml WHITELIST=RenderBasic

v2: add newlines to debug messages + fix comment (Matthew Auld)
