ASoC: rt5514: work around link error
The main rt5514 driver optionally calls into the SPI back-end to load the firmware. This causes a link error when one driver selects rt5514 as built-in and another driver selects rt5514-spi as a loadable module: sound/soc/codecs/rt5514.o: In function `rt5514_dsp_voice_wake_up_put': rt5514.c:(.text+0xac8): undefined reference to `rt5514_spi_burst_write' As a workaround, this adds another silent symbol, to force rt5514-spi to be built-in for that configuration. I'm not overly happy with that solution, but couldn't come up with anything better. Using 'IS_REACHABLE()' would break the case that relies on the loadable module, and all other ideas would result in more complexity.
