Suman Anna f853f00531 arm64: dts: ti: k3-am65-mcu: Add the MCU RAM node
Add the on-chip SRAM present within the MCU domain as a mmio-sram node.
The K3 AM65x SoCs have 512 KB of such memory. Any specific memory range
within this RAM needed by a software module ought to be reserved using
an appropriate child node.
