Note for each fence if it's a VM page table update or not. This allows
us to determine the last VM update in a sync object and so to figure
out if we need to flush the TLB or not.

drm/radeon: split semaphore and sync object handling v22014-11-20T18:00:16+00:00Christian Königchristian.koenig@amd.com2014-11-19T13:01:22+00:00urn:sha1:975700d2cc84408efa9b2360e38b1ab95368556f
Previously we just allocated space for four hardware semaphores
in each software semaphore object. Make software semaphore objects
represent only one hardware semaphore address again by splitting
the sync code into it's own object.
v2: fix typo in comment
