One of the v4.19 patches had a bug, this is fixed upstream,
but in OpenWrt we can fix it by just fixing the bug in the
patch.
We also need to augment the config file to select the
CONFIG_DRM_FBDEV_EMULATION symbol.
This restores the display controller on the DIR-685 to
working state: penguin and graphics on the little screen
with default OpenWrt install.

The command line enforced by the kernel is harmful, we want to
use the command line passed from the device tree. This is
especially important for the SQ201, Teltonika RUT and WBD111
which has a console set to 115200n8 and not 19200n8 like all
the others, so their consoles will be confusingly changing
baudrate between boot loader and kernel. The setting in the
device tree corresponds to what the boot loader is using.

CONFIG_PACKET is a important feature to have.
The Packet protocol is used by applications which
communicate directly with network devices without
an intermediate network protocol implemented in
the kernel, e.g. tcpdump and ip.

This moves some new configuration options to the generic kernel
configuration instead of configuring them for each target on our own.

CONFIG_BINFMT_MISC allows it to add support for new executable formats
to the kernel from user space, the kernel will then detect for example a
java binary and call the java execution program automatically. I am not
aware that this feature is used in OpenWrt and this could be used to
exploit something. Deactivate it for all targets for now.

Some targets deactivated CONFIG_SYN_COOKIES, for unknown reasons, use
the default setting from the generic configuration which activates
CONFIG_SYN_COOKIES.
This should prevent SYN flooding.

We currently generate a kernel that boots from the harddrive
in the DIR-685. That's not how we usually do things, so
let's augment it to boot from flash and mount the rootfs
using squashfs and JFFS2 like everyone else.
Partition splitting only work when the partitions are
inside of a "partitions" node which is why we have a patch
like this (submitted upstream).
Another patch drops the rootfs arguments and renames the
firmware partition while adding the compatible "wrg"
to it so the WRGG parser will kick in.
Factory image was tested by bravely reflashing the DIR-685
from stock firmware using the web UI and the serial console
boot loader.
