Nouveau - Sep 2025 - [PATCH v5 05/12] gpu: nova-core: firmware: move firmware request code into a function

When all the firmware files are loaded from `Firmware::new`, it makes
sense to have the firmware request code as a closure. However, since we
eventually want each individual firmware constructor to request its own
file (and get rid of `Firmware` altogether), move this code into a
dedicated function that can be called by individual firmware types.

I think just request_firmware() is fine.
