x86/platform/intel-mid: Make several arrays static, to make code smaller

Browse Source 
Don't populate arrays on the stack, instead make them static.
Makes the object code smaller by 76 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   4217	   1540	    128	   5885	   16fd	arch/x86/platform/intel-mid/pwr.o

After:
   text	   data	    bss	    dec	    hex	filename
   3981	   1700	    128	   5809	   16b1	arch/x86/platform/intel-mid/pwr.o
