As the RCLK clock may be updated through the common clk API before each
snd_soc_dai_ops::trigger call, it is not enough to update i2s->rclk_srcrate
only once after it has been initially set to 0. To avoid wrong PSR values
we always get the RCLK frequency from the CLK_I2S_RCLK_SRC, when this clock
is available.
