ARM: SoC fixes 

There are three more fixes for this week:
 
 - The Windows-on-ARM laptops require a workaround to
   prevent crashing at boot from ACPI
 - The Renesas "draak" board needs one bugfix for
   the backlight regulator
 - Also for Renesas, the "hihope" board accidentally
   had its eMMC turned off in the 5.3 merge window.
