arm64: dts: ti: Introduce J722S family of SoCs

The J722S is a family of application processors built for Automotive and
Linux Application development. J722S family of SoCs is a superset of the
AM62P SoC family and shares similar memory map, thus the nodes are being
reused from AM62P includes instead of duplicating the definitions.

Some highlights of J722S SoC (in addition to AM62P SoC features) are:
* Two Cortex-R5F for Functional Safety or general-purpose usage and
two C7x floating point vector DSP with Matrix Multiply Accelerator
for deep learning.
* Vision Processing Accelerator (VPAC) with image signal processor
and Depth and Motion Processing Accelerator (DMPAC).
* 7xUARTs, 3xSPI, 5xI2C, 2xUSB2, 2xCAN-FD, 3xMMC and SD, GPMC for
NAND/FPGA connection, OSPI memory controller, 5xMcASP for audio,
4xCSI-RX for Camera, 1 PCIe Gen3 controller, USB3.0 eCAP/eQEP,
ePWM, among other peripherals.
