I'll take a look at that, though given CXL doesn't have that much in DSDT that
is different from pxb-pcie (it is set to grow a bit, but just by one _DSM)
and the code is currently mixed up, it may make more sense to pull out both CXL
and PXB into a single SSDT.
I'm definitely keen on less churn in these files given it's not the
easiest thing to sort out if you care carrying a lot of patches out of
tree as we currently are for CXL.
