There are at least two types in the ADT related to USB,
but there's a decent chance that there are even more
required for other devices:
* A simple tunable that applies to a whole device node
and all its MMIO ranges specified in the "reg" property.
This one seems to just be mask32.
* A slightly more complex tunable that applies to a single
MMIO range specified in the "reg" property. So far I've
only seen 32 bit masks but the format looks like it should
also support 8,16 and 64 bit masks.
