[ Upstream commit fe17e6cdc0fefca96ba9659be4b2b07487cbf0c5 ]

when do randconfig like this: CONFIG_SND_SOC_SOF_IMX8_SUPPORT=y CONFIG_SND_SOC_SOF_IMX8=y CONFIG_SND_SOC_SOF_OF=y CONFIG_IMX_DSP=m CONFIG_IMX_SCU=y

there is a link error:

sound/soc/sof/imx/imx8.o: In function 'imx8_send_msg': imx8.c:(.text+0x380): undefined reference to 'imx_dsp_ring_doorbell'

Select IMX_DSP in SND_SOC_SOF_IMX8_SUPPORT to fix this
