cxl: Use to_pci_driver() instead of pci_dev->driver
Struct pci_driver contains a struct device_driver, so for PCI devices, it's easy to convert a device_driver * to a pci_driver * with to_pci_driver(). The device_driver * is in struct device, so we don't need to also keep track of the pci_driver * in struct pci_dev. Replace pdev->driver with to_pci_driver(). This is a step toward removing pci_dev->driver.
