ARM: SoC non-urgent fixes for v4.3

We normally collect non-urgent fixes during the release cycle and queue
them for the merge window.

This time around the list is short (in part because some have gone in other
branches).

- Maintainers addition for bcm2835
- IRQ number fix for orion5x (been present since 3.18)
- DT fix for display on exynos3250
- Exynos fix to use of IOMEM_ERR_PTR properly
