PCI: pciehp: Always implement resume, regardless of pciehp_force param
Previously, the driver ignored resume unless the pciehp_force module_param was specified. On some laptops that means that interrupts are not delivered after S3, so card removals and insertions are not handled. This patch makes the driver handle resume regardless of pciehp_force.
