Pull request: u-boot-sunxi/master for 2021.10 - 2nd part

[Andre Przywara]

Hi Tom,

please pull the second sunxi PR for the 2021.10 merge window.
I decided to merge most of Samuel's rework and some smaller patches that
pave the way for more DM transitions and for accommodating the RISC-V SoC
in the future. Merging them now gives us the opportunity to get some wider
testing, since those subtle changes tend to break things.

Compile-tested for all 159 sunxi boards, boot-tested on Pine64-LTS
and OrangePi Zero.

Summary:
- Add and enable watchdog driver
- Prepare for SYSRESET driven AXP poweroff
- Prepare for SoCs without MMC2
- Some fixes for extending SPL (SPL-DM for RISC-V)
- Some preparations for proper VBUS management
- Fix secure monitor move

Thanks,
Andre
