John Titor 0cd5621572 amd/cpu/raphael-igpu: enable scatter/gather for kernel 6.6+
Scatter/gather was introduced in 6.2 kernel and caused flickering
and various issues when running iGPU on Ryzen 7000-series CPUs.
This issue is not observed in kernel 6.6 or newer versions
so we can enable it for kernel 6.6 and newer versions.
