Merge branch '2022-09-23-4gb-ddr-in-32bit-ppc' into next

To quote the author, for the first 9 patches:
This patch series fixes U-Boot code to correctly handle RAM size larger
than 2 GB and then fixes fsl ddr driver to do not crash U-Boot when 4 GB
DDR module is detected when U-Boot operates in 32-bit mode (as opposite
of the 36-bit mode).

With this patch series it is possible to boot 32-bit U-Boot with 4 GB
SODIMM DDR3 module without crashes. U-Boot will still use just
CONFIG_MAX_MEM_MAPPED amount of RAM, but it is better than crashing due
to the truncating of 4GB value to 32-bit number (which is zero).

I tested this patch series on powerpc P2020 based board but only with
U-Boot v2022.04 because U-Boot master branch is still broken on P2020.

And then the final two patches here are (in my mind at least) related
clean-ups.
