drm: qxl: constify ttm_place structures. 

ttm_place are not supposed to change at runtime. All functions
working with ttm_place provided by <drm/ttm/ttm_placement.h> work
with const ttm_place. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   3485	    184	    264	   3933	    f5d	drivers/gpu/drm/qxl/qxl_ttm.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   3501	    152	    264	   3917	    f4d	drivers/gpu/drm/qxl/qxl_ttm.o
