[PATCH -next] ASoC: codecs: wcd934x: Fix Kconfig dependency

[Ren Zhijie]

If CONFIG_REGMAP_SLIMBUS is not set,
make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-,
will be failed, like this:

sound/soc/codecs/wcd934x.o: In function `wcd934x_codec_probe':
wcd934x.c:(.text+0x3310): undefined reference to `__regmap_init_slimbus'
make: *** [vmlinux] Error 1

Add select REGMAP_SLIMBUS to config SND_SOC_WCD934X.

Fixes: a61f3b4f476e ("ASoC: wcd934x: add support to wcd9340/wcd9341 codec")
