dmaengine: imx-sdma: remove the maximum limitation for bd numbers
No this limitation now after virtual dma used since bd is allocated dynamically instead of static. Signed-off-by: Robin Gong <yibin.gong@nxp.com> Reviewed-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Vinod Koul <vkoul@kernel.org>
