Karsten Keil c713f57ed5 sane irq initialization in sedlbauer hisax 
The interrupts schould be disabled until the driver
is ready and the IRQ function was registered.

Thanks to Bastian Friedrich  and Thomas Voegtle for spotting this.

* Speed Card ISAC_HSCX DIP-SWITCH
* Speed Win ISAC_HSCX ISAPNP
* Speed Fax+ ISAC_ISAR ISAPNP Full analog support
* Speed Star ISAC_HSCX CARDMGR
* Speed Win2 IPAC ISAPNP
* ISDN PC/104 IPAC DIP-SWITCH
* Speed Star2 IPAC CARDMGR
* Speed PCI IPAC PCI PNP
* Speed Fax+ ISAC_ISAR PCI PNP Full analog support

* Important:
* For the sedlbauer speed fax+ to work properly you have to download
* the firmware onto the card.
* For example: hisaxctrl <DriverID> 9 ISAR.BIN
