The STM32 I2S drivers use Common Clock Framework thus they cannot be
built on platforms without it (e.g. compile test on MIPS with RALINK and
SOC_RT305X):
/usr/bin/mips-linux-gnu-ld: sound/soc/stm/stm32_i2s.o: in function `stm32_i2s_hw_params':
stm32_i2s.c:(.text+0x1870): undefined reference to `clk_set_parent'

The new stm32_adfsdm driver has incomplete dependencies as shown
by Kconfig:
warning: (SND_SOC_STM32_DFSDM && LMP91000) selects IIO_BUFFER_CB which has unmet direct dependencies (IIO && IIO_BUFFER)
sound/soc/stm/stm32_adfsdm.o: In function `stm32_adfsdm_trigger':
stm32_adfsdm.c:(.text+0x8c): undefined reference to `stm32_dfsdm_get_buff_cb'
stm32_adfsdm.c:(.text+0x9c): undefined reference to `stm32_dfsdm_release_buff_cb'
This makes the dependency on SND_SOC_STM32_DFSDM unconditional, so we can
always resolve the stm32_dfsdm_get_buff_cb/stm32_dfsdm_release_buff_cb
symbols and get the implied IIO_BUFFER dependency.
compile-testing on other platforms is still possible as long as that IIO
driver is there.
