I2S controller has an internal mux for RCLK source clks. The list of source clk names were passed through platform data in non-dt case. The variable holding the list of RCLK source clk names is not required, as the list of clks need to be registered with clkdev using generic connection id. This is required as part of adding DT support for I2S controller driver.
