Hack for AlcorMicro AU9560 and Acos-ID card

Perform a double reset cold + hot so that the Acos-ID card uses a lower
communication speed.

The cold ATR of this card is:
3B DF 96 FF 91 01 31 FE 46 80 31 90 52 41 02 64 05 02 00 AC 73 D6 22 C0 17
While the hot ATR is:
3B DF 18 FF 91 01 31 FE 46 80 31 90 52 41 02 64 05 02 00 AC 73 D6 22 C0 99

Note how TA1 changed from 0x96 (250000 bits/s at 4 MHz) to 0x18
(129032 bits/s at 4.00 MHz).
