With imx-pcm-dma moving to generic dmaengine pcm driver and the removal of imx-pcm-audio/imx-fiq-pcm-audio platform device use, now imx-pcm driver contains a few functions that are only used by imx-pcm-fiq.c. Move these functions into imx-pcm-fiq.c and remove imx-pcm.c completely. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
