Enable spidev drivers to support BLE modules on SANTVEND boards.

Depending on the revision of hardware, different drivers should be used:
- in case of v1.2 revision, it is equipped with ISP091201 BLE module
which is governed by special "spidevas" driver which implements its own
chip select handling.
- in case of v1.3 revision, it is equipped with Protues-III BLE module,
which is governed by standard "spidev" driver.

It was decided to build the "spidevas" driver as a kernel module.

Approach ip filter config to seco-mx8m. CONFIG_LIBCRC32C=m seems to
be no longer necessary as it was automatically removed by menuconfig.

The kernel includes and recipes have been renamed to seconorth.
Also the defconfigs have been moved to fitting folders.

The most recent mainline LTS 5.15 kernel is 5.15.29. So use this one for
the limux-guf implementation.

The port is based on on a cleaned linux-guf 5.10.104.

Remove CONFIG_STACKPROTECTOR_PER_TASK defconfig as it breaks the build.

With this enabled and with the jump from Linux 5.10.57 to 5.10.104 I see
the following error:
```

Form my point of view this is a missing header inside the gcc-plugin
package, and should be fixed there. However, right now we just remove
the feature from the kernel.

Enabled wireguard in defconfig. Removed wireguard-modul dependencies for
wireguard-tools since wireguard is already integrated in kernel 5.10.

Add the in-kernel driver for the AD7879 resistive touch driver connected
via I2C. The AD7879 will replace the previous STMPE controller due to
EOL of the STPME.

SANTINO-LT is the first G&F iMX6 platform that uses a different UART
debug port, UART5 instead of UART2. It is not possible to use both port
settings together with early printk. Even though this is unfortunate,
we do not need the early printk feature enabled in production so diable
it here.

CONFIG_VT_HW_CONSOLE_BINDING and CONFIG_LEDS_TRIGGERS are still due to
default dependencies.

Add the USB3503 HSIC USB-hub driver. This should  enable the internal
USB port for SANTARO and SANTOKA. At least it works for SANTOKA.

It seems to mess with the out-of-tree SIS vendor driver. Thus get rid of
the in-kernel driver for now from the linux defconfig and use the
sis-i2c vendor driver instead.

The SMDMA needs a firmware blob. It could be added to the Linux kernel,
however it is easier to add the SDMA support as module.

Use the ```make savedefconfig``` to generate a minimal and portable
defconfig.

Add the linux-guf-5.10 recipe and copy the files form 5.4.

Do not use the
use-pkg-config-native-to-find-host-lcrypto-in-sysroot.patch because it
does not apply right now.

Also assign PREFERRED_VERSION of the linux-guf recipe weakly to be able
to overwrite this in the local.conf

Only tested with imx6guf.

When imx-sdma is built into the kernel the rootf, where the sdma
firmware binary is located is not ready when the driver tries to load
the firmware. This can be avoided by building the imx-sdma driver as a
module, so it gets loaded after the rootfs is ready

* Add simple-amplifier driver, which is now used together with

cherry-picked to out current kernel the aliasing works as it worked for
previous linux ports, namely the eMMC equipped on the iMX6 Garz & Fricke
boards is mapped to mmcblk0.

Thus use this mmcblk0 mapping to refer to the eMMC.

Rename the linux kernel repository to linux-guf.
Switch to SRCREV="${AUTOREV}" for the kernel development.

The team decision is to rename the linux kernel repository from
linux-stable to linux-guf to show that it actually does not mirror the
linux-stable directly but uses it as a basis source for our Garz &
Fricke development.

This changes include renaming the recipe, adjusting the Gitlab URL and
renaming the PREFERRED_PROVIDER_virtual/kernel.

With this change we also want to use the bitbake AUTOREV feature to pull
the latest development kernel. Right now we do not have the release
method to pin the revision to a specific version.

Pull the latest kernel including an increase of the Backlight PWM
frequency. Together with the activated panel-dt and the previously added
gfxml2dto more then one display can be supported,

* Allow usage of commandline from bootloader
* Adapt the default commandline:
** Remove earlyprintk, should be used for debug only

* Pull the rtc-pcf8563.c source from the kernel-tree at v5.4.23
 (bfe3046ecafdd71ba6932deebe2eb357048b7bfc)
* Remove the in-tree driver from the defconfig
* Add the module to the MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS for san* and
nallino platforms

- use new kernel version with all I2C devices present for testing on 400 kHz bus rate

- use new kernel with SIS9255 touch support and updated kernel's defconfig

- set kernel recipe to crurrent HEAD of GUF linux-stable
- set kernel defconfig to current guf_imx_v6_v7_defconfig
  - with appended device tree enabled
  - with default kernel command line
