I feel like we are going to be living with the ghosts of the original
"Type2 / Type3" naming problem for the rest of the subsystem's lifespan
especially since they were encoded in the ABI and ABI is forever.

I am not opposed to this localized rename in drivers/cxl/acpi.c on
principal, but in terms of incremental value relative to the thrash, it's
questionable.

For example changes to include/acpi/actbl1.h need to be chased through
ACPICA, at which point is this rename really worth it?
