The commit below, adds a call to sysclk callback on shutdown.
This introduces a regression in stm32 SAI driver, as some clock
services are called twice, leading to unbalanced calls.
Move processing related to mclk from shutdown to sysclk callback.
When requested frequency is 0, assume shutdown and release mclk.

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.
