The remaining cleanups for 3.19 are to a large part result of
devicetree conversion nearing completion on two other platforms
besides AT91:
* Like AT91, Renesas shmobile is in the process to migrate to DT and
multiplatform, but using a different approach of doing it one
SoC at a time. For 3.19, the r8a7791 platform and associated\
"Koelsch" board are considered complete and we remove the non-DT
non-multiplatform support for this.
* The ARM Versatile Express has supported DT and multiplatform
for a long time, but we have still kept the legacy board files
around, because not all drivers were fully working before. We
have finally taken the last step to remove the board files.
Other changes in this branch are preparation for the later branches
or just unrelated to the more interesting changes:
* The dts files for arm64 get moved into per-vendor directories for
a clearer structure.
* Some dead code removal (zynq, exynos, davinci, imx)
* Using pr_*() macros more consistently instead of printk(KERN_*)
in some platform code.
