In commit 94bccc340710 ("iscsi_ibft: make ISCSI_IBFT dependson ACPI instead
of ISCSI_IBFT_FIND") Kconfig was disentangled to make ISCSI_IBFT selection
not depend on x86.

Update arm64 acpi documentation, changing IBFT support status from
"Not Supported" to "Optional".
Opportunistically re-flow paragraph for changed lines.

Lorenzo, please could you ack the change below if you're happy with it?
If so, I can take it as a fix.

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).

Lorenzo

Thanks,

Will
