ASoC: Fix dependency for SND_SOC_RAUMFELD and SND_PXA2XX_SOC_HX4700

SND_SOC_RAUMFELD selects SND_SOC_CS4270 which needs CONFIG_I2C,
and also selects SND_SOC_AK4104 which needs SPI_MASTER.
Thus make SND_SOC_RAUMFELD depend on I2C && SPI_MASTER.

Add depend on SPI_MASTER to fix below build error if CONFIG_SPI_MASTER
is not selected.

SND_PXA2XX_SOC_HX4700 selects SND_SOC_AK4641 which needs CONFIG_I2C.
Thus make SND_PXA2XX_SOC_HX4700 depend on I2C.
