6dfcf70f63 qmod: Start with _HUB_RESET=0 -> HUB_RESET=1 (not in reset) 
Booting with the hub reset active would in turn cut our own power
supply as the hub disables all downstream port power in that case.

e974fbb9e5 Issue ST12_PRTPWR_OVERRIDE before putting hub in reset 
When we reset the hub, the hub will actively drvie the PRTPWR signal of
the SITMRACE12 low, resulting in the SAM3 being shut off.  If we want to
"survive" this, we need to set the OVERRIDE before we go into reset.

Right now, we never release the signal again, keeping ST12 enabled
permanently, which is of course not what we want in general.

226b40aba4 WIP: bit-banging I2C support for EEPROM access on QMOD 
for now, it just continuously reads the EEPROM bytes and dumps them to
the serial console for testing.

3bafe43376 dynamically dispatch USART IRQs 
The different modes (configurations) will have different interrupt
handlers, so we need to dispatch them via config_func_ptrs

tab-indent and 8-charracter tab width.

1605564489 ensure USB config numbers always start from 1 
Depending on which features (and thus USB configurations) are included
in the firmware, we need to re-define the ordering of the configuration
numbers, as the Atmel USBD driver simply assumes that configurations are
numbered 1..N without any gaps in the sequence.

40901a0f14 various printf/debug output improvements 
... among those is a rotor (\|/-) that is printed by the main loop,
so one can observe if the main loop is still executing or the system
is somehow stuck.

8d6a5d8f89 move USBDDriverCallbacks_ConfigurationChanged() to main.c 
This alows us to mark simtrace_config as static variable and keep all
code related to this variable local to main.c

3d8c093cb2 main: Increase timeout for USB configured state 
When the timeout was too small, the main function would infinitely
loop around, restarting the board and waiting for the USB interface
to get configured. But since configuration seems to take more than
one second, it rarely succeeded.
Increasing the timeout makes the USB configuration finish in the
first try.

95d6616ba1 Split init into configure and init 
* Implemented configure, init, exit functions:
    When a configuration is changed, interrupts for reset pins
    should be disabled

* Moved variables shared between code files to simtrace.h
