Subject: [PATCH] dt-bindings: Fix array property constraints

Schemas for array properties should only have 1 level of array
constraints (e.g. items, maxItems, minItems). Sometimes the old
encoding of all properties into a matrix leaked into the schema, and
didn't matter for validation. Now the inner constraints are just
silently ignored as json-schema array keywords are ignored on scalar
values.

Generally, keep the inner constraints and drop the outer "items". With
gicv3 "mbi-alias" property, it is more appropriately a uint32 or uint64
as it is an address and size depends on "#address-cells".
