[patch 2.4.28-pre3] 3c59x: reload EEPROM values at rmmod for needy cards

Enable reload of EEPROM values in reset at rmmod for cards that need
it, similar to old EEPROM_NORESET flag but in reverse.

(Most?) 3c905 and (some?) 3c905B cards need an additional bit unmasked
in the reset at rmmod or else they don't get reinitialized properly when
the driver is reloaded.

Please note that this depends on the "3c59x: resync with 2.6" patch
which I posted earlier today.
