Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

in case flashing the main application firmware using DFU failed,
the main application might be broken and not allow to switch again
to DFU mode to re-flash it correctly.
the other board have a way to force entering (e.g. staying in) the
bootloader using an external signal (e.g. a switch on the SIMtrace
board).
the OWHW DFU firmware did not have this functionality implemented.
the design (e.g. schematic) already has the SIMTRACE_BOOTLOADER
signal (on PA31) for this purpose.
now the DFU bootloader will start the DFU mode when the
SIMTRACE_BOOTLOADER is high.
this change has been tested on OWHWv2.

the LEDs (2 of them) were connected to the same pins on all
boards, up to the octsim-tester.
to be able to have board specific LEDs the definitions have moved
from common to the each board.
at the same time I added a bit of documentation what the LEDs are
used for.

UART baud rate is main clock (MCK) divided by CR*16.
The MCK values are chosen >= 48 MHz and <= 64 MHz to have a near
integer value CR for a baud rate of 921600 bps.
The end MCK frequency between simtrace and qmod differ slightly
but are close to 58 MHz.

This way we can easily check with 'diff' for differences in our code and
Atmel softpack. Also, this layout is more suitable for building various
different firmware images (e.g. factory-test, dfu-loader, main
application) for a variety of different boards (simtrace, owhw, qmod).
