[PATCH v1] serial: 8250_exar: Consistently define pci_device_ids using named initializers

["Uwe Kleine-König (The Capable Hub)" <u.kleine-koenig@baylibre.com>]

The .driver_data member of the struct pci_device_id array were
initialized by list expressions. This isn't easily readable if you're
not into PCI, still more given that it's hidden in macros. Using named
initializers is more explicit and thus easier to parse for a human. And
it's also more robust against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
pci_device_id that replaces .driver_data by an anonymous union.

Also drop a few explicit zeros that are not needed and improve
indention.

This change doesn't introduce changes to the compiled pci_device_id
array. Tested on x86 and arm64.
