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.

Notes:
Changes from v3:
* Add gpio, emmc and USB device in the DTS with upstream bindings
* Describe the irqmap for easy understanding and verification
* Update power-domains properties
Changes from v2:
* Only add the DT entries for devices with stable bindings
* Organize the DTS to match the bus topology with upstream kernel
Changes from v1:
* Split up the peripheral mem_region to match with kernel dts
* Add GPU, multimedia decoder and display devices

You should drop this node. The address is not mapped in
k3-j721e-evm-linux-demo.c and there are no users in this DT. You should be very
careful when virtualizing inta and udmass.
I am waiting for mcasp bindings to be supported in mainline kernel.
Once it is done, we will start using UDMA, inta, intr from linux-demo cell

hmm..is this working? IIRC GPIO group should be selected along with mux mode,
else it will be routed to GPIO0.
Good catch. Since many configs are not enabled in mainline kernel, I
missed these failures.
I enabled the configs an it is failing. I shall send the fixes
separately now that the series is merged in next
