TEMP: arm64: dts: ti: k3-am654-base-board: Increase reserve memory for RTOS IPC

A 1 MB of carveout memory at 0xa2000000 is reserved currently for achieving
IPC between the two MCU R5F cores when running in split-mode. The PDK IPC
RTOS code though is currently accessing some memory beyond this 1 MB, used
to also achieve IPC with the A53 cores running RTOS (Linux uses a separate
1 MB region per core as part of the overall 16 MB region). Reserve an
additional 1 MB of memory temporarily until the RTOS code logic is fixed
up to avoid memory corruptions with the linux kernel.
