[PATCH v1 1/2] dt-bindings: Add bindings for BrcmSTB SCMI mailbox driver

[PATCH v1 1/2] dt-bindings: Add bindings for BrcmSTB SCMI mailbox driver

Bindings are added.  Only one interrupt is needed because
we do not yet employ the SCMI p2a channel.

I thought SCMI was a mailbox consumer, not provider?

Drop the label and unit-address.

Run 'make dt_binding_check' as it will tell you the latter.
