ASoC: soc-io: Add CONFIG_REGMAP_I2C/CONFIG_REGMAP_SPI guards for regmap_init_i2c...

In the case of "make da8xx_omapl_defconfig;make", the SPI support is disabled.
Thus calling regmap_init_spi in soc-io.c has below build error.

ERROR: "regmap_init_spi" [sound/soc/snd-soc-core.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

This patch fixes the build error by adding CONFIG_REGMAP_I2C/CONFIG_REGMAP_SPI
guards for regmap_init_i2c/regmap_init_spi.
