ASoC: amd: ps: Fix -Wformat-truncation warning

Browse Source 
The compile warning with -Wformat-truncation at
sdw_amd_scan_controller() is false-positive; the max loop size is
AMD_SDW_MAX_MANAGERS (= 2), hence it fits with the given size.

For suppressing the warning, replace snprintf() with scnprintf().
As stated in the above, truncation doesn't matter.
