dtschema: Rework int array to matrix fixups
Using _is_int_schema to match int arrays doesn't work if we have a list
of 'items' with just descriptions as that looks the same as a string or
phandle list. To fix this, let's also look for a $ref to a 'uint*-array'
type in addition to integer keywords. As part of this, _fixup_int_array
becomes redundant and can be removed.
The items size fixup needs to be done after all the other fixups and after
all the recursion. Otherwise, we miss some instances.
