PCI: shpchp: Remove hpc_ops

Browse Source 
Remove the hpc_ops struct from shpchp. This struct is unnecessary and no
other hotplug controller implements it. A similar thing has already been
done in pciehp with 82a9e79ef1 ("PCI: pciehp: remove hpc_ops").

shpchp:
* There is only a single implementation of struct hpc_ops. Can the struct be
removed and its functions invoked directly? This has already been done in
pciehp with commit 82a9e79ef132 ("PCI: pciehp: remove hpc_ops"). Clarify
if there was a specific reason not to apply the same change to shpchp.
* The hardirq handler shpc_isr() queues events on a workqueue. It can be
simplified by converting it to threaded IRQ handling. Use pciehp as a
template.
