Implemented CPUs, RAM, UARTs and Interrupt Controller
Other peripherals are represented as TYPE_UNIMPLEMENTED_DEVICE
Complete memory map of the SoC is provided.
Set default RAM size to 2GB and default CPU count to 4 to match
the real i.MX8MM EVK hardware configuration.
Documentation is shared with imx8mp-evk to avoid duplication.
