msm: sps: Update debug message format specifier

Restrict printing of kernel virtual addresses in SPS driver.

In debug prints, handles to bam device structures may be printed
as integers. As these handles are obtained by casting pointer
to bam device structures to integer, they can reveal addresses
of the structures to attackers.

Cast the handles in debug prints to pointers, printed with with %pK,
which hides these values if kptr_restrict is set (default on Android).
