It is not good to have cpu_name and to_version encoded into sdma firmware name as variables. For example, there are three TOs of imx51 soc, the sdma script never changes since TO1, which means all three TOs of imx51 uses TO1 version of sdma script. But we have to prepare three identical firmwares, sdma-imx51-to1.bin sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel capable of running on all three TOs. The patch removes cpu_name and to_version from sdma platform data, and instead uses fw_name to pass the firmware name, so that we can pass the TO version where it's relevant and skip it where only one firmware exists.
