ARM: SoC changes for v5.13

Almost all SoC code changes this time are for the TI OMAP
platform, which continues its decade-long quest to move from
describing a complex SoC in code to device tree.

Aside from this, the Uniphier platform has a new maintainer
and some platforms have minor bugfixes and cleanups that were
not urgent enough for v5.12.
