Subject: [PATCH] ASoC: rt5677: add SPI_MASTER dependency

When CONFIG_SPI is disabled, the newly added code for the DSP
firmware loading fails to link:

ERROR: "rt5677_spi_hotword_detected" [sound/soc/codecs/snd-soc-rt5677.ko] undefined!
ERROR: "rt5677_spi_write" [sound/soc/codecs/snd-soc-rt5677.ko] undefined!

Add a dependency to prevent this configuration.

Note: the does not work with the DT probing, as there is no binding
for the SPI half of the driver, but nothing seems to be using that
with the mainline kernel anyway.

Fixes: 461c623270e4 ("ASoC: rt5677: Load firmware via SPI using delayed work")
