Rename the pad to sw_data as per description of this field in the hardware spec(refer sprugr9 from www.ti.com). Latest version of the document is at http://www.ti.com/lit/ug/sprugr9h/sprugr9h.pdf and section 3.1 Host Packet Descriptor describes this field. Define and use a constant for the size of sw_data field similar to other fields in the struct for desc and document the sw_data field in the header. As the sw_data is not touched by hw, it's type can be changed to u32. Rename the helpers to match with the updated dma desc field sw_data.
