Specifying both clocks as IMX6QDL_CLK_SDMA results in driver incorrectly thinking that ratio is 1:1 which results in broken SDMA funtionality(this at least breaks RAVE SP serdev driver on RDU2). Fix the code to specify IMX6QDL_CLK_IPG as "ipg" clock for SDMA, to avoid detecting incorrect clock ratio.
