Subject: [PATCH] ASoC: improve RT5514 dependencies

With SND_SOC_RT5514_SPI=m and SND_SOC_RT5514=y, we get this link error:

sound/soc/codecs/rt5514.o: In function `rt5514_dsp_voice_wake_up_put':
rt5514.c:(.text+0x2068): undefined reference to `rt5514_spi_burst_write'
rt5514.c:(.text+0x20c8): undefined reference to `rt5514_spi_burst_write'

This adds another Kconfig symbol to work around the link error, forcing
the main driver to be a loadable module as well if some other driver
selects the I2C side to be built-in.

Fixes: 2a18483a7fb4 ("ASoC: Intel: Add Kabylake machine driver for RT5514, RT5663 and MAX98927")
Signed-off-by: Arnd Bergmann <arnd@...db.de>

This can now lead to a configuration with
SND_SOC_INTEL_KBL_RT5663_RT5514_MAX98927_MACH=y and SND_SOC_RT5514=m. I
don't know if that is a problem or not.

An alternative approach would be to flip the dependency between
rt5514_spi.ko and rt5514.ko and avoid having the rt5514_spi_burst_write
symbol exported.
