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.
