PCI: shpchp: Remove unused get_mode1_ECC_cap callback
The ->get_mode1_ECC_cap callback in the shpchp_hpc_ops struct is never called, so remove it.

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 ->get_mode1_ECC_cap callback in shpchp_hpc_ops is never invoked.
- Why was it introduced? Can it be removed?
-
* 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.
