drm/radeon/kms/r6xx+: use new style fencing (v3)
On r6xx+ a newer fence mechanism was implemented to replace
the old wait_until plus scratch regs setup. A single EOP event
will flush the destination caches, write a fence value, and generate
an interrupt. This is the recommended fence mechanism on r6xx+ asics.
This requires my previous writeback patch.
v2: fix typo that enabled event fence checking on all asics
rather than just r6xx+.
v3: properly enable EOP interrupts
Should fix:
