Develop code: 1. to identify the type of SOC (RK3588 / RK3588M / RK3588J) 2. print the information

sample log:

CPU: Rockchip RK3588J rev1.2 at 792MHz CPU: Industrial temperature grade (-40C to +85C) at 28C

use this for reference: https://github.com/radxa/kernel/blob/linux-5.10-gen-rkr4.1/drivers/cpufreq/rockchip-cpufreq.c#L231

Goal is to identify the chip and load right DTB

If RK3588, then ncm6a dtb If RK3588J, then ncm6b dtb

So, create another issue with this support

Why we need build steps here? document it in readthedocs.
