All the Rockchip SoC support reset cauee like POR_RST, GLB_RST, TSADC_RST, WD_RST by reading the clock reset unit register.

V2: with the feedback from Jonas Karlman and Quentin Schulz drop the inply for CONFIG_DISPLAY_CPUINFO as it defaault enabled. re-organized the code.

As pointed only as of now RK3328, RK3399 supports this feature for POR and RST.

On RK3568 and RK3588 SoC it only return POR, for all the case of reboot and poweroff. I have tried to debug this issue, found Clock Reset Unit will bind to rockchip_sysreset to determine the reset cause. if there is ant input on this please share.

I have update two new patches from u-boot-radxa, but with no success.

Tested on Rock64, Rock-3a, Rock-5b boards.

I have update few Rockchip SoC to verify this feature, Only Build to since I dont have the hardware.

Thanks -Anand
