The included opal.h gives a wrong idea that CXL makes PPC OPAL calls

But it does use eg.
OPAL_PHB_CAPI_MODE_SNOOP_ON
OPAL_PHB_CAPI_MODE_CAPI
Which come from opal-api.h via opal.h.
So you should at least include opal-api.h.
I'd say that since it includes pnv-pci.h (and this is why this patch
compiles), it should be a different set of values for powernv (which
would map 1:1 to OPAL_PHB_xxx). The powernv platform knowledge is
already intimate enough for a driver to have. Dunno, I found this opal.h
inclusion confusing, that's all.
I agree, it would be the cleaner way of doing it. It's going to be
pretty low on my list though...
