[ena] Use pci_bar_set() to place device within bridge memory window

Use pci_bar_set() when we need to set a device base address (on
instance types such as c6i.metal where the BIOS fails to do so), so
that 64-bit BARs will be handled automatically.

This particular issue has so far been observed only on 6th generation
instances.  These use 32-bit BARs, and so the lack of support for
handling 64-bit BARs has not caused any observable issue.
