The intent of the default here is that it matches what ioremap() does on 
other platforms already (where it does not make any claims of being 
posted, though it could be on some platforms). It could be per-platform 
what that means... but either way it should be what drivers get today 
without asking for anything special.

I agree, but yeah... that's one big refactor to try to do now...

Yes; the implementation was trying to be generic, but AIUI we don't need 
this on M1 because the PCI mappings don't go through this codepath, and 
nothing else needs posted mode. My first hack was something not too 
unlike this, then I was going to get rid of apple,arm-platform and just 
have this be a generic mechanism with the properties, but then we added 
the optimization to not do the lookups on other platforms, and now we're 
coming full circle... :-)

If you prefer to handle it this way for now I can do it like this. I 
think we should still have the DT bindings and properties though (even 
if not used), as they do describe the hardware properly, and in the 
future we might want to use them instead of having a quirk.
