Did I write before that I think this is an ugly hack that should be
removed in the future by converting *all* drivers to DM? :-)

Please fix the format here: all defines should be formatted the same way
(i.e. here: 0x00, 0x0c, 0x20 etc) to make the code easier to read.

This even gets uglier now by adding the section placement. I have a
series (still not finished) to fully convert gen5 to driver model, where
I will get rid of this, then we will get an #ifndef around this one that
disables it for gen5.
Do you have any plans like that for a10/s10/agilex?
