So long as all the fixes; changes to the driver and DT are merged in a
single kernel release, we can change it.

Scrap that, change of plan. Actually current code is correct.

mbox-name does not have the same functionality as mbox-names.

mbox-names is a client-side property used to request channels, where
as mbox-name is used to provide a better user-readable name other than
mailbox{0..x}.
