Add the linux demo cell config for j721e-evm board.
Also add the required device tree for booting Linux kernel
in the inmate cell.
This cell config acts as a reference for partitioning
devices across the 2 Linux cells.
This will be updated as support for more devices get added.

This is too recent for "older" kernels, even 4.19. We are building this
unconditional, though, so we need to avoid breaking such builds. I'm
importing the needed defines into this file.
