accel/ivpu: Don't enable any tiles by default on VPU40xx
commit eb0d253ff9c74dee30aa92fe460b825eb28acd73 upstream.
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.
Fixes: 79cdc56c4a54 ("accel/ivpu: Add initial support for VPU 4")
