dt-bindings: mailbox: add Versal IPI bindings

Add documentation for AMD-Xilinx Versal platform Inter Processor Interrupt
controller. Versal IPI controller contains buffer-less IPI which do not
have buffers for message passing. For such IPI channels message buffers
are not expected and only notification to/from remote agent is expected.

dt-bindings: mailbox: zynqmp: extend required list

"xlnx,ipi-id" is handled as required property but is
missing from binding doc required list of mailbox child node.
Add that to required list. This does not break backward
compatibility but bug in bindings document.

dt-bindings: zynqmp: add destination mailbox compatible

Current dt-bindings does not contain compatible property
for child mailbox node. Child mailbox nodes are used
to represent destination (remote) IPI agents. The compatible
property for all destination mailboxes must be required to
identify the node.

This addition of new required property does not break ABI
as current driver does not use this compatible property
but, new features in driver should use this property.

dt-bindings: Add missing (unevaluated|additional)Properties on child node schemas

Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present.

Add unevaluatedProperties or additionalProperties as appropriate, and
then add any missing properties flagged by the addition.
