Subject: [PATCH] ARM: dts: Add devicetree for the Raspberry Pi 3, for arm32 (v3)

Raspbian and Fedora have decided to support the Pi3 in 32-bit mode for
now, so it's useful to be able to test that mode on an upstream
kernel.  It's also been useful for me to use the same board for 32-bit
and 64-bit development.

v1: Gerd's patch that put the ../../../arm64/... link in the Makefile
v2: Michael's patch that #included from ../../../arm64/... in a new
    bcm2837-rpi-3-b.dts.
v3: Mine, using symlinks to make sure that we don't break the split DT
    tree.
