filetype: mvebu: Fix kwbimage v1 detection ...

The kwbimage detection calculates a checksum over the first 31 bytes of
the image. This is correct for the v0 image format, but for the v1 image
format the checksum in the image also covers the extenstion headers.
These might not be completely present in the initial buffer provided to
file_detect_type(), so just drop the checksum calculation for v1 images.

filetype: support fastboot barebox_update with layerscape image ...

We do not yet support USB on the Layerscape platforms, but when we do,
it's imaginable that we would want to export barebox_update targets over
Fastboot. Prepare for this by adding the layerscape images to those that
filetype_is_barebox_image returns true for.

filetype: add STM32 image type ...

Both STM32MP BootROM and TF-A first stage expect subsequent bootloader
stages to feature a specific 256-byte long STM32 file header.
Add detection of the header to file_detect_type().

While there's only one version of the header so far, identify the new
header as v1 anyway, so new versions can be unambiguously added.

Add filetype and detection for squashfs images ...

This adds `filetype_squashfs` to the list of known filetypes and adds a
detection for squashfs files to file_detect_type(). This currently
matches on the `hsqs` start sequence of an image file.

Additionally, the newly introduced filetype is registered as the type of
the squashfs_driver which allows, for example, to mount squashfs without
the need to specify a type parameter.

This changes enable booting a squashfs with the simple `boot` command
pointing to the location (device) that holds the squashfs.

Note that booting with blspec is limited as the current squashfs driver
is not capable of handling symbolic links.

Deleted pieces of code detect MBR-containig device as a FAT-type device,
if it's first partition contains a FAT filesystem. This behaviour enabled one
to mount the FAT FS which is either directly on the device (disk0) or on
the first partition (disk0.0) using the same command:
    mount /dev/disk0 /fat
However, the desired behaviour can be reached with a:
    mount /dev/disk0 /fat || mount /dev/disk0.0 /fat || echo "Mounting failed"
