ARM: SoC fixes for 5.0 

This week is a much smaller update, containing fixes only for TI OMAP,
 NXP i.MX and Rockchips platforms:
 
  - omap4 had problems with lost timer interrupts
  - another IRQ handling issue with OMAP5
  - A workaround for a regression in the pwm-omap-dmtimer driver
 
  - eMMC was broken on the new imx8mq-evk board
 
  - a fix for new dtc graph warnings and a regulator fix for rock64
  - USB support broke on rk3328-rock64
