drm/mm: add ig_frag selftest
This patch introduces fragmentation in the address range
and measures time taken by 10k and 20k insertions. ig_frag()
will fail if the time taken by 20k insertions takes more than
4 times of 10k insertions as we know that insertions should at
most scale quadratically.
v2:
introduce fragmentation by freeing every other node.
only test bottom-up and top-down for now.
v3:
fix incorrect mode check
