U-Boot SPL binary does not read BIN header arguments, so passing some dummy
values 0000005b and 00000068 has no effect for U-Boot SPL code.
Probably these two values comes from old Marvell DDR training code which
was separated from U-Boot and used it for some configuration.
Seems that two 32-bit values were specified here to ensure SPL code
alignment to 128-bit boundary as it is required e.g. for A370 or AXP
processors. Main kwbimage header is 64-byte long which is aligned to
128-bit boundary. Optional kwbheader is 32-bit long, number of BIN header
arguments is stored in 32-bit number. So for alignment to 128-bit boundary
is needed 64-bit padding which exactly these two 32-bit dummy arguments
provided.
Now when mkimage correctly aligns start of executable code in BIN header to
128-bit boundary, there is no requirement to put dummy argument values into
kwbimage. So remove them.

Move the gdsys Controlcenter DC specific build time kwbimage.cfg
generation code into the mach-mvebu/ directory to be shared by all 32bit
mvebu platforms.
Remove board specific kwbimage.cfg files, and use the generated one
instead. These files are all identical, with two exceptions. Clearfog
and Helios4 use the sdio boot device, whereas all others use spi. Update
the defconfigs for the exceptional boards to generate the same
kwbimage.cfg as before.
