cpufreq: speedstep-lib: make several arrays static, makes code smaller

Browse Source 
Don't populate arrays on the stack, instead make them static.
Makes the object code smaller by over 860 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  10716	   5196	      0	  15912	   3e28	drivers/cpufreq/speedstep-lib.o

After:
   text	   data	    bss	    dec	    hex	filename
   9690	   5356	      0	  15046	   3ac6	drivers/cpufreq/speedstep-lib.o
