It is to workaround HW bug on other Asics and based on
reverting two commits:
drm/amdkfd: Add heavy-weight TLB flush after unmapping
drm/amdkfd: Add memory sync before TLB flush on unmap

Original patch will cause regressions on Aldebaran as well, so this workaround is still invalid.

Hi Felix,
I was not able to reproduce the VM fault issue of SWDEV-249241, which is
the only regression reported on MI200. So the patch is valid to review.
Please take a look.
Thanks,
Eric
