Subject: [PATCH v3 0/3] MIPS: Move device-tree files to a common location

To be consistent with other architectures and to avoid unnecessary
makefile duplication, move all MIPS device-trees to arch/mips/boot/dts
and build them with a common makefile.  Per Olof's suggestion in v1,
device-trees are grouped into per-vendor subdirectories, based on the
kbuild changes introduced by Robert Richter's series for arm64 DTS
vendor subdirectories [0].  The makefiles for MIPS must be adjusted
slightly from what is used for arm{,64} since most MIPS platforms
require builtin device-tree binaries.  This introduces two bits of
ugliness: a) *.dtb.o files are still generated by 'make dtbs' since
there is no longer a 'dtbs' target for the .../boot/dts makefile, and
b) the dummy.o trick to force kbuild to make an empty built-in.o.
I'd be interested in any suggestions to avoid these, since I"m by
no means a makefile/kbuild expert.

Patch 1 sets up the makefiles for building the DTs in arch/mips/boot/dts
and introduces the config option BUILTIN_DTB for platforms that require
it.

Patch 2 introduces the 'dtbs' and 'dtbs_install' makefile targets.

Patch 3 moves the DTs out of the platform directores.

I've build tested this on all affected platforms (Octeon, Lantiq, SEAD3,
Netlogic, and Ralink) as well as Malta.  For platforms where builtin DTBs
are optional (Netlogic and Ralink), I built with and without the builtin
DTBs.

Based on 3.17-rc5.

Changes from v2:
 - added 'dtbs_install' target
 - squashed move of dts files into a single patch
 - rebased on 3.17-rc5 + Robert's dts vendor subdir support
Changes from v1:
 - moved to per-vendor subdirectories
 - rebased on 3.17-rc2
