[2.6 patch] misc ISAPNP cleanups

[Adrian Bunk <bunk@stusta.de>]

The patch below removes some completely unused code and makes some 
needlessly global code static in drivers/pnp/isapnp/core.c .

Please review whether this patch is correct or whether it conflicts with 
pending ISAPNP updates/usages.
