ARM: SoC fixes for v5.7

This time there is one fix for the error path in the mediatek cmdq driver
(used by their video driver) and a couple of devicetree fixes, mostly
for 32-bit ARM, and fairly harmless:

- On OMAP2 there were a few regressions in the ethernet drivers,
  one of them leading to an external abort trap

- One Raspberry Pi version had a misconfigured LED

- Interrupts on Broadcom NSP were slightly misconfigured

- One i.MX6q board had issues with graphics mode setting

- On mmp3 there are some minor fixes that were submitted for
  v5.8 with a cc:stable tag, so I ended up picking them up
  here as well

- The Mediatek Video Codec needs to run at a higher frequency
  than configured originally
