[PATCH -next] ASoC: SOF: imx8: Fix COMPILE_TEST error

[YueHaibing]

When do compile test, if SND_SOC_SOF_OF is not set, we get:

sound/soc/sof/imx/imx8.o: In function `imx8_dsp_handle_request':
imx8.c:(.text+0xb0): undefined reference to `snd_sof_ipc_msgs_rx'
sound/soc/sof/imx/imx8.o: In function `imx8_ipc_msg_data':
imx8.c:(.text+0xf4): undefined reference to `sof_mailbox_read'
sound/soc/sof/imx/imx8.o: In function `imx8_dsp_handle_reply':
imx8.c:(.text+0x160): undefined reference to `sof_mailbox_read'

Make SND_SOC_SOF_IMX_TOPLEVEL always depends on SND_SOC_SOF_OF
