Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxiWIP/12Nov2023

To quote Andre:

The first few patches are some easy refactorings and fixes, most of them
actually don't change the generated binaries at all. Then there is a
defconfig for a new board, for which we just gained the .dts file from
the last kernel DT sync.
On top there is support for a new PMIC (AXP313), and LPDDR4 support for
the Allwinner H616 SoC, both of which are needed to support new devices
that appeared lately, especially cheap TV boxes.

While those are technically new features, they don't affect existing
boards, for instance the LPDDR4 support code is guarded by a new DRAM
type Kconfig variable. So the risk for regressions is very slim.

Gitlab CI passed, and I booted that briefly on some boards, including an
H616 and an H618 one (with LPDDR4).
