dt-bindings: Improve phandle-array schemas

The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. Many schemas for
phandle-array properties aren't clear in the schema which case applies
though the description usually describes it.

The array of phandles case boils down to needing:

items:
  maxItems: 1

The phandle plus args cases should typically take this form:

items:
  - items:
      - description: A phandle
      - description: 1st arg cell
      - description: 2nd arg cell

With this change, some examples need updating so that the bracketing of
property values matches the schema.
