ARM: SoC fixes for 4.13

This comes a bit later than I planned, and as a consequence is a larger
 than it should be.
 
 Most of the changes are devicetree fixes, across lots of platforms:
 Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic Meson,
 Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
 
 Also across many platforms, I applied an older series of simple randconfig
 build fixes. This includes making the CONFIG_MTD_XIP option compile again,
 which had been broken for many years and probably has not been missed, but
 it felt wrong to just remove it completely.
 
 The only other changes are:
 
  - We enable HWSPINLOCK in defconfig to get some Qualcomm boards
    to work out of the box.
 
  - A few regression fixes for Texas Instruments OMAP2+.
 
  - A boot regression fix for the Renesas regulator quirk.
 
  - A suspend/resume fix for Uniphier SoCs, fixing the resume of the
    system bus.
