[PATCH 3/8] amdgpu/pm: Optimize emit_clock_levels for arcturus - part 2

Thu Apr 27 06:27:13 UTC 2023
Use variables to remove ternary expression in print statement and
improve readability. This will help to optimize the code duplication
in the switch statement
Also Changed:
replaced single_dpm_table->count as iterator in for loops with safer
clocks_num_levels value
replaced dpm_table.value usage with local var clocks_mhz
