Kind of strange to have this separated out. I guess you have non-PSCI
firmware too? In any case, unless things have changed, upstream is only
supporting spin-table or PSCI for arm64. So please combine this with the
rest of the cpu nodes.
This was copied from older Tegras - we might have had some systems in
the past with non-PSCI firmware, but certainly don't have that anymore.
I'll combine the nodes.
