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