arm64: dts: ti: iot2050: Add/enabled mailboxes and carve-outs for R5F cores
Analogously to the am654-base-board, configure the mailboxes for the two
R5F cores, add them and the already existing memory carve-outs to the
related MCU nodes. Allows to load applications under Linux onto the
cores, e.g. the RTI watchdog firmware.
