    drm/xe: avoid plain 64-bit division
    
    Building the xe driver for i386 results in a link time warning:
    
    x86_64-linux-ld: drivers/gpu/drm/xe/xe_migrate.o: in function `xe_migrate_vram':
    xe_migrate.c:(.text+0x1e15): undefined reference to `__udivdi3'
    
    Avoid this by using DIV_U64_ROUND_UP() instead of DIV_ROUND_UP().  The driver
    is unlikely to be used on 32=bit hardware, so the extra cost here is not
    too important.
    
    Fixes: 9c44fd5f6e8a ("drm/xe: Add migrate layer functions for SVM support")
