Subject: [PATCH] ARM: dts: rockchip: Add Rockchip RV1126 SoC

RV1126 is a high-performance vision processor SoC for IPC/CVR,
especially for AI related application.

It is based on quad-core ARM Cortex-A7 32-bit core which integrates
NEON and FPU. There is a 32KB I-cache and 32KB D-cache for each core
and 512KB unified L2 cache. It has build-in NPU supports INT8/INT16
hybrid operation and computing power is up to 2.0TOPs.

This patch add basic core dtsi support.
