cxl: Remove use of macro DEFINE_PCI_DEVICE_TABLE

cxl: Remove use of macro DEFINE_PCI_DEVICE_TABLE

Macro DEFINE_PCI_DEVICE_TABLE is deprecated. So, here use
struct pci_device_id instead of DEFINE_PCI_DEVICE_TABLE with
the goal of getting rid of this macro completely.

The Coccinelle semantic patch that performs this transformation
is as follows:

@@
identifier a;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer i;
@@
- DEFINE_PCI_DEVICE_TABLE(a)
+ const struct pci_device_id a[]
= i;
