This patch add support to manage LLI by SW for select phy channels. There is a HW issue in certain controllers due to which on certain occassions HW LLI cannot be used on some physical channels. To avoid the HW issue on a specific phy channel, the phy channel number can be added to the list of soft_lli_channels and there after all the transfers on that channel will use software LLI, for peripheral to memory transfers. SoftLLI introduces relink overhead, that could impact performace for certain use cases. This is based on a previous patch of Narayanan Gopalakrishnan.
