PNP: remove pnp_resource.index

We used pnp_resource.index to keep track of which ISAPNP configuration
register a resource should be written to.  We needed this only to
handle the case where a register is disabled but a subsequent register
in the same set is enabled.

Rather than explicitly maintaining the pnp_resource.index, this patch
adds a resource every time we read an ISAPNP configuration register
and marks the resource as IORESOURCE_DISABLED when appropriate.  This
makes the position in the pnp_resource_table always correspond to the
config register index.
