mailbox: ti-msgmgr: Add ti,tda54-main-secure-proxy support

Browse Source 
Add support for the TDA54 secure proxy mailbox controller integrated in
the MAIN voltage domain. This instance supports up to 444 threads with
60-byte messages per thread. Add the corresponding device data for the
ti,tda54-main-secure-proxy compatible.

While at it, update some internal variable types from u8 to u16 to hold
values up to 444.
