amdgpu/pm: Optimize emit_clock_levels for arcturus - part 1

Browse source 
Use variables to remove the multiple nested ternary expressions and
 improve readability. This will help to optimize the code duplication
 in the switch statement
 Also Changed:
  Modify function arcturus_get_clk_table to void function as it
    always returns 0
  Use const string "attempt_string" to cut down on repetition
