prism-firmware: added support of loading 1.8.4 firmware for Prism2/3 CF cards on insert

This will give possibility of using WPA/WPA2 for users which cards have firmware
older then 1.7.4 (which was first version with WPA support).
It is alternative to reflashing cards.

Tested on Prism2 and Prism3 cards, replace all previous ways of supporting them.
