Pull arm-soc board specific changes from Olof Johansson:
"While we generally attempt to get rid of board specific files and
replace them with device tree based descriptions, a lot of platforms
have not come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination
of DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not
adding new ones."
Fix up trivial conflicts in arch/arm/mach-{mmp/ttc_dkb.c,shmobile/{Kconfig,Makefile}}
