Subject: [PATCH v3 2/3] gpu: nova-core: select RUST_FW_LOADER_ABSTRACTIONS

RUST_FW_LOADER_ABSTRACTIONS was depended on by NOVA_CORE, but NOVA_CORE
is selected by DRM_NOVA. This creates a situation where, if DRM_NOVA is
selected, NOVA_CORE gets enabled but not RUST_FW_LOADER_ABSTRACTIONS,
which results in a build error.

Since the firmware loader is an implementation detail of the driver, it
should be enabled along with it, so change the "depends on" to a
"select".

Fixes: 54e6baf123fd ("gpu: nova-core: add initial driver stub")
