[PATCH v3] accel/ivpu: Add missing MODULE_FIRMWARE metadata

[Alexander F. Lent]

Modules that load firmware from various paths at runtime must declare
those paths at compile time, via the MODULE_FIRMWARE macro, so that the
firmware paths are included in the module's metadata.

The accel/ivpu driver loads firmware but lacks this metadata,
preventing dracut from correctly locating firmware files. Fix it.

Fixes: 9ab43e95f922 ("accel/ivpu: Switch to generation based FW names")
Fixes: 02d5b0aacd05 ("accel/ivpu: Implement firmware parsing and booting")
