right justified and aligned with preceding please. While adding new
code to a existing driver it is a good idea to conform to existing style

so if another version has this feature we would do:
        if (jzdma->version == ID_JZ4770) ||
                if (jzdma->version == ID_JZXXXX))

and so on.. why not add a value, clk_enable in the description and use
that. For each controller it is set to true or false
