[PATCH] shpchp: remove redundant data structures

Browse Source 
State information is currently stored in per-slot as well as
per-pci-function data structures in shpchp. There's a lot of
overlap in the information kept, and some of it is never used.
This patch consolidates the state information to per-slot and
eliminates unused data structures. The biggest change is to
eliminate the pci_func structure and the code around managing
its lists.
