lightnvm: move device L2P detection to core
A 1.2 device is able to manage the logical to physical mapping table internally or leave it to the host. A target only supports one of those approaches, and therefore must check on initialization. Move this check to core to avoid each target implement the check. Signed-off-by: Matias Bjørling <mb@lightnvm.io> Signed-off-by: Jens Axboe <axboe@kernel.dk>
