Andre Przywara d785a06a5a sunxi: remove common.h inclusion
The usage of the common.h include file is deprecated, and has already
been removed from several files.

Get rid of all inclusions in the arch/arm/mach-sunxi directory. Most
files actually don't need the header at all, for the few others just
include the headers that we actually require.
