Add copyright headers to various files.

I'd like to package sunxi-tools for Debian and therefore it is important for
the licensing information to be complete/accurate. I believe the intention was
for everything here to be GPL2+ by default, since that is the license on every
file which has one and COPYING contains GPL2.

Early on the license applied to this repo was GPLv3 however this was changed to
GPL2+ by Alejandro in 79ea14d4 at which point he had been the only
contributor.

This patch adds the standard GPL2+ stanza used already in sunxi-tools.git or
the MIT license stanza when requested by the copyright holder to various files
which were missing one as follows:

adb-devprobe.sh
fel-gpio
    According to git all of these were written by Henrik. Copyright years
    according to git. Henrik requested that these be put under an MIT license,
    so that is what has been done.

boot_head.lds
fel-pio.lds
fel-sdboot.lds
jtag-loop.lds
    According to git all of these were written by Henrik. Copyright year...
