[PATCH] dt-bindings: mailbox: Delete old 'mailbox.txt' bindings file

As per mailing-list discussions [1] [2] [3], we want to delete the
following old file from the device-tree bindings that live in the
Linux kernel git tree:
* Documentation/devicetree/bindings/mailbox/mailbox.txt

The old .txt file did have some descriptive text about what some of
the properties meant. Those have been added to the dt-schema
repository in a pull request [4].
