[PATCH v4 05/11] drm/i915: Add 'render basic' Haswell OA unit config

[Robert Bragg <robert@sixbynine.org>]

Adds a static OA unit, MUX + B Counter configuration for basic render
metrics on Haswell. This is 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 SYSFS=0 WHITELIST=RenderBasic
