[Intel-gfx] KMS start locks up RocketLake-S GT1

[Felix Miata]

Is there a command line option needed for RocketLake-S GT1 on i5-11400? Is it
supposed to use some module other than i915? Tumbleweed kernel 5.15.6 locks up,
apparently when KMS should be kicking in. I can't get any logs or dmesg except
when booting with nomodeset.
