clang-16 warns about casting between incompatible function types:
drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadow.c:161:10: error: cast from 'void (*)(const struct firmware *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
161 | .fini = (void(*)(void *))release_firmware,
This one was done to use the generic shadow_fw_release() function as a
callback for struct nvbios_source. Change it to use the same prototype
as the other five instances, with a trivial helper function that actually
calls release_firmware.
Fixes: 70c0f263cc2e ("drm/nouveau/bios: pull in basic vbios subdev, more to come later")

Applied to drm-misc-fixes, thanks!
