Subject: [PATCH] arm64: dts: ti: Add DTB overlays for vision apps and edgeai
apps
Confine the memory map changes into a separate rtos-memory-map.dts
which describes the common memory map for all RTOS remoteprocs.
vision-apps.dtbo uses this and also disables capture and display
related peripherals from Linux so that it can be used by RTOS.
edgeai-apps.dtbo expects these devices to be owned by linux, so
it uses the rtos-memory-map customization only.
