[PATCH V3 0/5] ARM: dts: bcm2835: Add Raspberry Pi Zero

This patch series add support for Raspberry Pi Zero with USB host mode. It's
based on the patch "ARM64: dts: bcm: Use a symlink to R-Pi dtsi files
from arch=arm" from Ian Campbell. Currently there is a bug [1] which needs
to fixed before because after applying these patch series the bug isn't
reproducible anymore but not fixed.

The patches 1-3 fixes the USB DT settings for bcm283x. Patch 3 is only compile
tested, so it would be nice if someone with a RPi 3 could test it.
The last patch based on the work of Lubomir Rintel [2] and Noralf Tr?nnes [3].

Note: Patch 3 can't be cherry-picked because it depends on Patch 2.

Changes since V2:
- rebase on "ARM64: dts: bcm: Use a symlink to R-Pi dtsi files from arch=arm"
- add dtsi file to easily specify host mode for bcm283x boards
- drop all dwc2 changes (incl. USB otg/gadget support) because of known
  issues [4]
- add copyright and license to new dts file

Changes since V1:
- rebase to current linux-next
- add patches 1 - 4 for otg/gadget support
- add patch 5 with model compatible
- use polarity define for ACT LED

All looks reasonable to me at a quick glance. I didn't validate any of 
the GPIO values etc.
