PCI hotplug: acpiphp: don't cache hotplug_params in acpiphp_bridge

Browse Source 
We always look up hotplug_params with decode_hpp() immediately before using
them, so we don't need to save them in the acpiphp_bridge struct.  This
patch follows the example of program_fw_provided_values() in pciehp_pci.c
and shpchp_pci.c by just keeping the params on the stack while we need them.
