Do we expect other boards to have a different memory reservation? I can see that
EVB and Kukui uses the same. If not, we should add the node in mt8183.dtsi instead.

All our current boards use the same memory reservation, but it's still
possible for future boards based on mt8183 to use different SCP memory
size, so I feel this should still be left out of mt8183.dtsi.

Applied to v5.9-next/dts64
I squashed this fix with the first patch to maintain bisectability.
Thanks!
