board_lowlevel: Clean up PLLA configuration
...
The PLL setting doesn't depend on the 'qmod' board type but on the
combination of the BOARD_MAINOSC and BOARD_MCK #defines. So let's
remove the '#ifdef qmod' from the equation.
The only 'qmod' specific part is whether or not to use the internal xtal
oscillator or not.

qmod: Don't violate PLL minimum output frequency
...
Table 42-31 ofd DOC6500 states that the minimum output frequency of the
PLL is 60 MHz. The existing qmod code violated this by configuring the
PLL multiplier output to 12*4 = 48 MHz. Let's use 12*8 = 96 and then
divide that by two to get to the desired 48 MHz.
This might help to resolve the non-working USB on the qmod so far.

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.

Add support for 'qmod' (quad-modem) board

You can compile the firmware for this new target using 'make

The QMOD differs from simtrace+owhw in terms of low-level
initialization, as it has an external 12MHz clock at XIN, thus bypasses
the main oscillator and needs different PLL configuration.

At higher speeds, it seems we are turning off the transmitter before we
are enabling the receiver. Unfortunately the TXEN bit in the uart mode
register is read-only, so we don't really know if the transmitter is
enabled or not. It seems we can simply keep transmitter + reciver
running at the same time, and use the TXEMPTY bit as reliable means to
determine if we're busy transmtting.
