Rob Herring 7f464532b0 dt-bindings: Add missing 'additionalProperties: false'
Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

description: |
This interrupt controller is found in the Intel IXP4xx processors.
Some processors have 32 interrupts, some have up to 64 interrupts.
The exact number of interrupts is determined from the compatible
string.
The distinct IXP4xx families with different interrupt controller
variations are IXP42x, IXP43x, IXP45x and IXP46x. Those four
families were the only ones to reach the developer and consumer
market.
