The-going e31992ae7c sun55iw3: move patches to archive/sunxi-dev-6.16 folder
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.
