[PATCH net-next 04/10] arm64: dts: mt7986: move cpuboot in a dedicated node

[Lorenzo Bianconi]

Since the cpuboot memory region is not part of the RAM SoC, move cpuboot
in a deidicated syscon node.
This patch helps to keep backward-compatibility with older version of
uboot codebase where we have a limit of 8 reserved-memory dts child
nodes.
