ASoC: stm32: dfsdm: don't use %pK through printk 



In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.

Switch to the regular pointer formatting which is safer and
easier to reason about.
