I don't see any issue with this patch, more so given that the IBFT
legacy discovery method was decoupled from the ACPI table method,
so it looks sound on ARM64.
However, I would like to get Al and Ard opinions on this to make sure
there is not something I am missing (in particular wrt the rationale
behind the "Not Supported" in the docs).
