drm/xe/tuning: Stop applying CCCHKNREG1 tuning from Xe3p onward
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.
