Kévin Redon b7f94dcb9f qmod: lower VCC threshold to 2.5V ...

on the QMOD board the VCC signal from the modem is measured using
an ADC (SIMtrace board just use card detect).
the threshold to consider VCC as activated was set to 2.8V, which
gives a bit of margin for the expected 3.0V.
still, we had one board where the voltage was 2.8V.
to be resilient against lower than expected voltages from
modems (or boards), we lowered the threshold to 2.5V.
this is still save for the SAM3S to correctly identify high/low
levels.
