dmaengine: mpc512x: Remove chancnt affectations
chanctnt is already filled by dma_async_device_register, which uses the channel list to know how much channels there is. Since it's already filled, we can safely remove it from the drivers' probe function. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
