When patches outside the series are in the target folder
KERNELPATCHDIR = "archive/sunxi- $ {KERNEL _ MAJOR _ MINOR}"
they create problems for all other patches in the series
and are difficult to move to the new kernel version because
they are not properly designed.
Move the patches to a separate development folder until
the design is fixed so that we can add them to the series.
