Merge branch 'newsoc/pxa1908' into soc/newsoc

This adds initial support for the Marvell PXA1908 SoC and
"samsung,coreprimevelte", a smartphone using the SoC.

*Important note*: There is a regression on all of the v6.16 RCs where
the board does not boot unrelated to the patches in this set. See:
https://lore.kernel.org/regressions/3367665.aeNJFYEL58@radijator/

USB works and the phone can boot a rootfs from an SD card, but there are
some warnings in the dmesg:
