This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.

The advantage is that these specifiers are machine-parseable which helps
license conformance, e.g. for packaging barebox in Debian.

While touching these files also do some minor comment reformatting to
get some uniform layout.

The Santaro has two different possible Touchscreen controllers.
Both are on different I2C addresses.  Let's probe both of them
and enable in the device tree the one that's actually found on
the hardware.

This file originates in Linux.  Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.

This commit was generated by the following commands:

  find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
  git mv include/sizes.h include/linux/

Instead of repeating the same lowlevel init for every board
move it to it's own initcall.

Avoids code bloat and shaves off almost 1.5kB of uncompressed
barebox size for a default imx_v7_defconfig build.

For boards wherethe hostname setup was done in  the postcore
initcall we move this to a device initcall to get it out of
the way.

The i.MX barebox update handlers take an optional dcd table as argument.
This can be used to add the correct dcd data to the image before flashing
it.
This mechanism is quite complicated and largely unused, so remove it. With
this it is only possible to flash the exact image passed to barebox_update,
which is what is mostly done anyway.

Most devices relevant for barebox like sd/emmc/network/uarts
work. Devicetree contains several undefined drive strength settings,
these can be fixed once the kernel has sorted this out.
