CXL test needs to be updated to work with latest RCH changes.
Add CXL test support for devm_cxl_add_rch_dport and
cxl_rcd_component_reg_phys functions.

My sob was accidentially added while working on the patches
internally. I have merged some reverting hunks with the previous
patch. The sob order can be changed or my sob can even be dropped. I
am fine with both.
Thanks,

This chain is getting confusing.
Why a SoB from Robert on this one?
As Terry sent the series I'd expect Terry to be last unless there
was some codevelopment involved in which case that should be indicated
in the tags.
For weird corner cases it's worth adding some comments on why a SoB chain
is non obvious.
I'm far from an expert on cxl-test so I'll leave reviewing this in
depth to others. FWIW looks fine to me.

This was a mistake on my part. I'll remove Robert. Thanks for pointing out.
