ASoC: stm32: sai: fix master clock management
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.

Takashi Iwai 18183edaad ASoC: stm: Drop superfluous PCM preallocation error checks
snd_pcm_lib_preallocate_pages() and co always succeed, so the error
check is simply redundant.  Drop it.

ASoC: Convert a few more users to using %pOFn instead of device_node.name
In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

ASoC: stm32: sai: fix invalid use of sizeof in stm32_sai_add_mclk_provider()
sizeof() when applied to a pointer typed expression gives the
size of the pointer, not that of the pointed data.

ASoC: stm32: sai: fix less than zero comparison on unsigned int
Currently, the comparison of div < 0 is always false because div is
an unsigned int. Fix this by making div an int.
