[PATCH 1/3] drm/xe/tuning: Stop applying CCCHKNREG1 tuning from Xe3p onward

[Matt Roper <matthew.d.roper@intel.com>]

Whereas the tuning guide gave guidance on adjusting various CCCHKNREG1
on past platforms, starting from Xe3p the guidance is "Leave register at
HW default settings."  Set a version range upper bound of "34.99" so
that the current programming will stop being applied on any Xe3p
platforms that have graphics version 35.
