pwm: Consistently define pci_device_ids using named initializers

The .driver_data member in the various struct pci_device_id arrays were
initialized by list expressions. This isn't easily readable if you're
not into PCI. Using named initializers is more explicit and thus easier
to parse.

The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.

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