drm/mgag200: make a const array static, makes object smaller 



Don't populate the const array m_div_val on the stack but instead make
it static. Makes the object code smaller by 29 bytes:

Before:
   text	   data	  bss   dec    hex filename
  34736	   4552	    0 39288   9978 drivers/gpu/drm/mgag200/mgag200_mode.o

After:
   text	   data	  bss   dec    hex filename
  34625	   4616	    0 39241   9949 drivers/gpu/drm/mgag200/mgag200_mode.o

(gcc version 10.2.0)
