arm64: dts: ti: k3-j721e: Add the MCU SRAM nodej721-next
Add the on-chip SRAM present within the MCU domain as a mmio-sram node.
The K3 J721E SoCs have 1 MB of such memory. Any specific memory range
within this RAM needed by a driver/software module ought to be reserved
using an appropriate child node.
