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

This updates the "old style" DTs to that of Linux v6.10, matching what
OF_UPSTREAM is at now. Hopefully we won't need to do this (manually)
anymore. Since this brings in the DT for a new board (Tanix TX1), also
add the defconfig for that, which has just been waiting for that sync.
There are three more fixes: two for the SPI clock setup, which avoids
too high frequencies in some cases, and one fix to avoid a build warning
with GCC 14 for the sunxi TOC0 part of the mkimage tool.

The gitlab CI passed, and I tested the SPI flash on the OrangePi Zero 3
and also booted that into Linux.
