sniffing: decrease USB IRQ prioprity to prevent USART overrun
...
Change-Id: I870a0aa8e251bbb53249c54bfcaa45de5b5a9486
Handling the USB message queue is done in an ISR and take quite some time.
This can cause a USART/SIM sniffing buffer overrun, resulting in data loss.
By setting the USB IRQ lower than the USART IRQ, the USB ISR can be
interrupted (for short) and no data gets lost.

sniff: use USART 0 instead of USART 1
...
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.
