Adrian Schmutzler cf7c101135 layerscape: remove useless pairs of kernel patches
The layerscape kernel patches appears to be just some uncleaned local
development tree, where patches are sometimes directly followed by
their revert. While this does not seem a problem in the first place,
it becomes incredibly unpleasant when the upstream kernel changes in
the relevant areas and requires rebase.

This removes all these patch-revert pairs and refreshs the rest.

It removes about 44000 lines of entirely useless code.
