When master clock is used, master clock rate is set exclusively.
Parent clocks of master clock cannot be changed after a call to
clk_set_rate_exclusive(). So the parent clock of SAI kernel clock
must be set before.
Ensure also that exclusive rate operations are balanced
in STM32 SAI driver.

Another batch of changes for ASoC, no big core changes - it's mainly
small fixes and improvements for individual drivers.
- A big refresh and cleanup of the Samsung drivers, fixing a number of
issues which allow the driver to be used with a wider range of
userspaces.
- Fixes for the Intel drivers to make them more standard so less likely
to get bitten by core issues.
- New driver for Cirrus Logic CS35L26.

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.
