I believe that most of the SPCR parsing should be generic, so maybe you
could extend the DEVICE interface to handle the ACPI case.

Extending DT_DEVICE would be confusing IMHO. The answer is probably a
similar but parallel ACPI_DEVICE mechanism, perhaps sharing some
underlying infrastructure with DT_DEVICE.

I was thinking to rename DT_DEVICE into something more meaningful. Because infine, DT_DEVICE_START/DT_DEVICE_END doesn't do anything DT specific but defined the a printed name and the device class.

So we can extend the device framework without adding too much new code.
