3c509: convert to isa_driver and pnp_driver

Convert 3c509 driver to isa_driver and pnp_driver.  The result is that
autoloading using udev and hibernation works with ISA PnP cards.  It also adds
hibernation support for non-PnP ISA cards.

xcvr module parameter was removed as its value was not used.

Tested using 3 ISA cards in various combinations of PnP and non-PnP modes.
EISA and MCA only compile-tested.
