[PATCH 03/17] arm64: dts: marvell: add syscon compatible to CP110 ICU node

[Miquel Raynal]

Prepare the migration to new bindings where the ICU node has several
subnodes: one per interrupt group (NSR, SEI, REI, etc). The code for
each node will share the same set of registers. Turning the ICU node
into a syscon is a clean solution to handle that.
