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.

-Subject: [PATCH] net: mscc: ocelot: do not force Felix MACs at lower speeds
- than gigabit
-
-In the LS1028A, the VSC9959 switch was integrated with an NXP PCS which
-performs SGMII AN and rate adaptation autonomously. The MAC does not
-need to know about this, and forcing the MAC speed to something else,
-when connected to a 10/100 link partner, actually breaks the GMII
-internal link between the MAC and the PCS.
-
-Add a quirk system in the ocelot driver, and a first quirk called "PCS
-performs rate adaptation", to distinguish the VSC7514 from the VSC9959
-regarding this behavior.
