ISAPNP: pull pnp_add_card_id() out of isapnp_parse_card_id()

Browse Source 
Split the pnp_add_card_id() part from the PNPID conversion part so we
can move the initial add_id() into the pnp_card allocation.

This makes the PNPID conversion generic so we can use the same
one for both devices and cards.
