PCI hotplug: acpiphp: remove superfluous _HPP/_HPX evaluation

decode_hpp() looks up hotplug PCI parameters from ACPI and saves them
in the acpiphp_bridge structure.  These parameters (in bridge->hpp) are
only used by the acpiphp_set_hpp_values() -> program_hpp() path.  In
that path, we always call decode_hpp() before program_hpp(), so there's
no need to do it in init_bridge_misc().
