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.

This patch is based on a patch from the U-Boot and fixes two errors with
the LCDC. Original commit message from Jyri Sarha [1]:
"Initialize EMIF OCP_CONFIG registers REG_COS_COUNT_1, REG_COS_COUNT_2,
and REG_PR_OLD_COUNT field for Beaglebone-Black and am335x-evm. With
the default values LCDC suffers from DMA FIFO underflows and frame
synchronization lost errors. The initialization values are the highest
that work flawlessly when heavy memory load is generated by CPU. 32bpp
colors were used in the test. On BBB the video mode used 110MHz pixel
clock. The mode supported by the panel of am335x-evm uses 30MHz pixel
clock."

The register values are generated by testing, because there is no formula
to calculate them. Also from Jyri Sarha [1]:
"In practice the only rule to find an optimal value is to find as high as
possible REG_PR_OLD_COUNT value that does not produce LCDC FIFO
underflows under worst case scenario. The worst case happens when the
highest pixel clock videomode with maximum bpp is used while memory
subsystem is stressed by endless stream of writes hitting the same
memory memory bank (can be the same address)."

It only contains the BeagleBone Black and the Phytec SoM, because I
don't have other boards.

The main idea behind this patch is to avoid redundant board code.
Because of the module similarities of all am335x based phytec boards, we can
merge its code.
The phytec-som-am335x merges the code of all am335x based phytec SOMs.
So we will have only one "board" in the barebox for phyCORE, phyFLEX.
