No, not at this commit: it describes the phy patch that comes later.
v9 folds this change into that phy patch, so the description and the
code now arrive together.

Yes, with only this patch applied. Because v9 folds it into the phy
patch, which removes the PSE lookup from fwnode_mdio, no commit has this
probe and remove cycle any more.

Yes, I could reproduce the hang with only this patch applied. The same
fix applies: in v9 this change is part of the phy patch, and with that
patch the PHY no longer waits for the PSE controller at all, so there is
nothing to loop on. A boot test with a PSE controller that never binds
now boots at every commit.
