EDAC: Rework workqueue handling
Hide the EDAC workqueue pointer in a separate compilation unit and add
accessors for the workqueue manipulations needed.
Remove edac_pci_reset_delay_period() which wasn't used by anything. It
seems it got added without a user with
91b99041c1d5 ("drivers/edac: updated PCI monitoring")
