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.
