dt-bindings: Add missing array size constraints

DT properties which can have multiple entries need to specify what the
entries are and define how many entries there can be. In the case of
only a single entry, just 'maxItems: 1' is sufficient.

Add the missing entry constraints. These were found with a modified
meta-schema. Unfortunately, there are a few cases where the size
constraints are not defined such as common bindings, so the meta-schema
can't be part of the normal checks.
