Linux standard header for the registers of PCI Data Object Exchange
(DOE). This header might be generated via script. The DOE feature
should be added in the future Linux release so this patch can be
removed then.

Hopefully we'll get some traction on the kernel support next cycle as doesn't
look like we'll get the reviews to move it forward this time.

This is indeed part of what we are proposing there so FWIW

these headers are imported from linux pls don't edit them
directly - get a patch into linux first.

For now you can add the defines to where they are used.
