drm/msm/dpu: Don't use %pK through printk (again)

Browse Source 
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("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.

This was previously fixed in this driver in commit 1ba9fbe403
("drm/msm: Don't use %pK through printk") but an additional usage
was reintroduced in commit 39a750ff5f ("drm/msm/dpu: Add DSPP GC
driver to provide GAMMA_LUT DRM property")
