ARM: SoC-related driver updates

Browse source 
Various driver updates for platforms:
 
  - A larger set of work on Tegra 2/3 around memory controller and
  regulator features, some fuse cleanups, etc..
 
  - MMP platform drivers, in particular for USB PHY, and other smaller
  additions.
 
  - Samsung Exynos 5422 driver for DMC (dynamic memory configuration),
  and ASV (adaptive voltage), allowing the platform to run at more
  optimal operating points.
 
  - Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas
 
  - Clock/reset control driver for TI/OMAP
 
  - Meson-A1 reset controller support
 
  - Qualcomm sdm845 and sda845 SoC IDs for socinfo
