[PATCH V2] ASoC: SOF: Fix build error with CONFIG_SND_SOC_SOF_NOCODEC=m

[YueHaibing]

Fix gcc build error while CONFIG_SND_SOC_SOF_NOCODEC=m

sound/soc/sof/core.o: In function `snd_sof_device_probe':
core.c:(.text+0x4af): undefined reference to `sof_nocodec_setup'

Change IS_ENABLED to IS_REACHABLE to fix this.
