[ISDN] Hisax: eliminate many unnecessary references to CardType[]

For the vast majority of CardType[card->typ] uses (but not all!),
the string is constant for each driver.  Therefore, we may replace
CardType[card->typ] with the actual string describing the driver, making
each printk() a bit more simple.

This also has the nice, intended side effect of greatly reducing
external references to hisax global CardType[].  This will be of value
once the ISDN drivers are converted to the ISA/PCI/PNP hotplug APIs.
