[PATCH RFC v2 00/23] Enable display cpuinfo to get the reset cause

[Anand Moon <linux.amoon@gmail.com>]

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
