layerscape: clean up kernel patches
A previous patch disaggregated kernel patch 601 intending to reverse the ndo_get_stats64 change, but it also dropped many other changes without a reason. This caused build issue for layerscape. This patch is to fix that with below steps. 1. Reversed patch "1c4415a layerscape: reverse changes to ndo_get_stats64", but kept kernel patch 701 which was a proper fix. 2. Reversed the ndo_get_stats64 change in kernel patch 601. 3. Renamed patch 601 (net patch) to 202 (core-linux patch). Maybe it's more proper. Fixes: 1c4415a679f9 ("layerscape: reverse changes to ndo_get_stats64") Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>

-Subject: [PATCH] net: centralize net_device min/max MTU checking
-
-While looking into an MTU issue with sfc, I started noticing that almost
-every NIC driver with an ndo_change_mtu function implemented almost
-exactly the same range checks, and in many cases, that was the only
-practical thing their ndo_change_mtu function was doing. Quite a few
-drivers have either 68, 64, 60 or 46 as their minimum MTU value checked,
-and then various sizes from 1500 to 65535 for their maximum MTU value. We
-can remove a whole lot of redundant code here if we simple store min_mtu
-and max_mtu in net_device, and check against those in net/core/dev.c's
-dev_set_mtu().
-
-In theory, there should be zero functional change with this patch, it just
-puts the infrastructure in place. Subsequent patches will attempt to start
-using said infrastructure, with theoretically zero change in
-functionality.

-Subject: [PATCH] base: soc: Introduce soc_device_match() interface
-
-We keep running into cases where device drivers want to know the exact
-version of the a SoC they are currently running on. In the past, this has
-usually been done through a vendor specific API that can be called by a
-driver, or by directly accessing some kind of version register that is
-not part of the device itself but that belongs to a global register area
-of the chip.
-
-Common reasons for doing this include:
-
-- A machine is not using devicetree or similar for passing data about
- on-chip devices, but just announces their presence using boot-time
- platform devices, and the machine code itself does not care about the
- revision.
-
-- There is existing firmware or boot loaders with existing DT binaries
- with generic compatible strings that do not identify the particular
- revision of each device, but the driver knows which SoC revisions
- include which part.
-
-- A prerelease version of a chip has some quirks and we are using the same
- version of the bootloader and the DT blob on both the prerelease and the
- final version. An update of the DT binding seems inappropriate because
- that would involve maintaining multiple copies of the dts and/or
- bootloader.
-
-This patch introduces the soc_device_match() interface that is meant to
-work like of_match_node() but instead of identifying the version of a
-device, it identifies the SoC itself using a vendor-agnostic interface.
-
-Unlike of_match_node(), we do not do an exact string compare but instead
-use glob_match() to allow wildcards in strings.
