Merge https://source.denx.de/u-boot/custodians/u-boot-sunxi

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.

Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.

Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).
