[netdrvr] skfp: remove a bunch of dead code
The driver has not compiled in anything except PCI support for many years (see drivers/net/skfp/Makefile). This driver is also unmaintained for many years, so arguments for keeping the cross-OS, cross-bus (ISA, EISA, MCA) code do not exist. Signed-off-by: Jeff Garzik <jeff@garzik.org>
