Merge branch 'arm/defconfig-cleanup' into arm/defconfig

I have continued the cleanup of the multi_*_defconfig files, and
reordered the other files according to the 'make savedefconfig'
output as before.

Since a third of the defconfig files are for machines that
are now marked as unused, I skipped those files. There are still
a few things that get removed by 'make savedefconfig' as they
now get selected by some driver:

-CONFIG_SERIAL_BCM63XX=y
-CONFIG_SND_AUDIO_GRAPH_CARD=m
-CONFIG_NEW_LEDS=y
-CONFIG_LEDS_TRIGGERS=y
-CONFIG_TEGRA20_APB_DMA=y

I think for those we should follow up with patches to remove the
'select' statements.
