[PATCH 1/2] dt-bindings: mailbox: ti,secure-proxy: Add TDA54 variant compatible

[Beleswar Padhi <b-padhi@ti.com>]

Add the ti,tda54-main-secure-proxy compatible for the secure proxy
mailbox controller integrated in the MAIN voltage domain of the TI TDA54
SoC, which features up to 444 threads with 60-byte messages per
thread.

The number of threads is fixed at SoC integration and cannot be
discovered at runtime, therefore a separate compatible is needed.
