Instead of using the timer/counter peripheral to handle the waiting time
and corresponding timeout, the USART peripheral internal timeout
mechanism is used.
This is particularly important for the SIMtrace board since there
(contrary to other boards) the I/O signal is not wired to a TIO pin
of the timer/counter block, and hence Rx/Tx data cannot reset that
timer/counter.
As a result of this migration, cardem is now supported not only on
owhw + qmod, but also on the simtrace board.
The guts of this change have been lifted out of Change-Id
Ibcb2c8cace9137695adf5fb3de43566f7cfb93b5 by Kevin Redon, which was
unfortunately touching various different topics at the same time and
hence was split up. Some improvements are the introduction of the
ENABLE_TX_TIMER_ONLY mode, which avoids the USART interrupt handler
getting hammered with TXRDY between release of RST and start of the ATR.

This unifies the printing of the welcome banner, and it also ensures
that all modes print all information (serial number, reset cause).
Furthermore the APP and BOARD #defines from the make environment are
also printed.

"SIMtrace 2 compatible device" is pretty generic. Let's have the
actual board name inside the string descriptors, giving a more
user friendly experience in case users are issuing 'lsusb' and the
like.

This string dates back to some very early naming; let's reflect how
we have been calling this in reality for quite some time now.

There have been tons of format-string related bugs in our code which
we never discovered due to disabling -Wformat. Let's fix that.

The red and green LEDs are now used as follows:
- red on = power (firmware is running)
- red blink = error detected (e.g. during ISO-7816 parsing)
- green on = running (sniffer mode is running)
- green blink = activity (e.g. USB message sent)

Use USART 0 connected to the SIM card side to sniff the communication.
The card side can also measure ETU times.
Do proper pin initialization.
This code can already capture the ATR communication between phone and card.

because the applications share the board capabilities defined in
libboard/*/include/board.h and USB configurations are enabled according
to the previously defined capabilities in libcommon/source.usb.c, all
applications actually offer the same functions.
thus creating the trace application is only mainly a cosmetic change, as the
sniffer function will also be present and enabled in the cardem application.
