ARM: SoC platform updates 

SoC updates, mostly refactorings and cleanups of old legacy platforms,
 but also a few more things:
 
 New SoC support this release:
  - NXP/Freescale i.MX7ULP (1x Cortex-A7, Cortex-M4, graphics, etc)
  - Allwinner F1C100, older platform with an ARM926-EJS (ARMv5) core
 
 Cleanups of various platforms:
  - OMAP1 ams-delta does some GPIO cleanups
  - Davinci removes of at24 platform data
  - Samsung cleans up old wakeup, PM debug and secondary core boot code
  - Renesas moves around config options and PM code to drivers/soc for
    sharing with 64-bit and more consistency
  - i.MX, Broadcom and SoCFPGA all have tweaks to lowlevel debug console setups
  - SoCFPGA adds explicit selection of ARM errata and removes some unused code
 
 This tag also contains a few patches that I had queued up as fixes for
 4.20 but didn't send in before the release.
