In case of the prep descriptor while the channel is already running, the CCR register value stored into the channel could already have its EN bit set. This would lead to a bad transfer since, at start transfer time, enabling the channel while other registers aren't yet properly set. To avoid this, ensure to mask the CCR_EN bit when storing the ccr value into the mdma channel structure.

Applied, thanks!
