ASoC: rt5677: Fix build error without CONFIG_SPI
If CONFIG_SPI is n, SND_SOC_RT5677_SPI also is n, building fails: sound/soc/codecs/rt5677.o: In function `rt5677_irq': rt5677.c:(.text+0x2dbf): undefined reference to `rt5677_spi_hotword_detected' sound/soc/codecs/rt5677.o: In function `rt5677_dsp_work': rt5677.c:(.text+0x3709): undefined reference to `rt5677_spi_write' This adds stub helpers to fix this.
