The mailbox DT node data has been added for OMAP2420,
OMAP2430, OMAP3430/OMAP3630, OMAP44xx devices. Data for
OMAP5 is skipped for now since the corresponding hwmod
entry is not present.
The mailbox static device initialization logic is also
adjusted for a DT boot.

If this is always 4, why do you want to expose that?
BTW, I guess that most of these attribute are generic enough to avoid
the "ti," prefix.
