From: Andrzej Kacprowski <Andrzej.Kacprowski@xxxxxxxxx> There is no point in requesting 1 tile on VPU40xx as the FW will probably need more tiles to run workloads, so it will have to reconfigure PLL anyway. Don't enable any tiles and allow the FW to perform initial tile configuration. This improves NPU boot stability as the tiles are always enabled only by the FW from the same initial state.
