arm64: dts: freescale: Add NXP S32N79-RDB board support

Browse Source 
Add device tree support for the NXP S32N79 Reference Design Board
(RDB) [1].

The S32N79-RDB enables the following peripherals:
- PL011 UART controllers (uart0, uart5, uart6, uart7)
- uSDHC controller
- IRQ steering controller

The board has 32GB of DRAM memory with 28GB usable and 4GB reserved
for ECC logic.
