scsi: hisi_sas_v3_hw: Don't use PCI helper functions
Drivers using new-framework/generic-framework should not handle standard
power management operations. These operations were performed by legacy
framework through PCI helper functions like pci_save/restore_state(),
pci_set_power_state(), etc.
Drivers should not use them now.
