Subject: [PATCH v2 4/8] arm64: dts: add NXP S32G2 support

Add an initial dtsi file for generic SoC features of NXP S32G2.

Signed-off-by: Chester Lin <clin@...e.com>
---
Changes in v2:
- Add a SoC description.
- Add an interrupt-affinity to the pmu node.
- Move the psci node into the "/firmware" node.
- Remove the redundant properties and white lines.
- Remove the wrong interrupt specifier from the gic node.
- Specify the range and cell-size of /soc [0 - 4 GiB].
- Correct the reserved size of GICR to 512KiB [0x80000].
