ARM: SoC platform updates SoC changes, a substantial part of this is cleanup of some of the older platforms that used to have a bunch of board files. In particular: - Removal of non-DT i.MX platforms that haven't seen activity in years, it's time to remove them. - A bunch of cleanup and removal of platform data for TI/OMAP platforms, moving over to genpd for power/reset control (yay!) - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them closer to multiplatform support (not quite there yet, but getting close). THere are a few other changes too, smaller fixlets, etc. For new platform support, the primary ones re: - New SoC: Hisilicon SD5203, ARM926EJ-S platform. - Cpufreq support for i.MX7ULP
