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.

UPLI PHY connected to USBH1 on Babbage board seem to need a special
reset sequence in which STP signal gets asserted for a short period of
time. Without this sequnce running "usb" results in timeout and no USB
devices found.

Similar reset sequences can be found in Babbage board code in U-Boot
as well as efikamx_usb_init() in Barebox.

After being introduced 3 years ago this feature ended up being
"obsoleted by events" and project it was supposed to be a part of
winded down.

Revert this feature due to:

  a) Lack of users

  b) Existence of better way to make barebox load via SRAM as
  intermediary step that does not require two separate images to be
  built (.imx-sram-img)

This reverts commit 903c947.

Some board designs copy i.MX51 Babbadge board's PMIC design and so
require exactly the same initialization. Move correspoding code into a
separate file so it can be shared.

All i.MX images are nowadays built with the imx-image tool, so we do not
need the header files and Kconfig options anymore. Remove them.

This commit add a very basic code to allow Barebox to be booted from
IRAM. Given that the amount of IRAM on most i.MX variants is
insufficient to contain a copy of Barebox with any reasonable degree
of functionality this code uses IRAM only as a temporary location and
eventually bootstraps from DRAM. But the presense of the intermediate
IRAM-only stage allows to add provisions to test the area of DRAM that
Barebox would be using to facilitate various testing scenarious.

imx_v7_defconfig covers the babbage board, no need for a board defconfig.

This makes sure the PMIC is initialized once it's available. Move the
initcall to coredevice_initcall to make sure we initialize the PMIC
before the FEC driver is initialized. The ethernet phy needs vgen3
enabled in the PMIC initialization.

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.

This renames the Freescale and Phytec board directories and defconfig
files to a common naming scheme. The board directories are named
<vendor>-<board> and the defconfig files are named
<vendor>-<board>_defconfig. Also the DataModul realq7 is renamed to its
Marketing Name eDM-QMX6.
