present: Support async flips
The xserver Present code only calls radeon_present_flip with
sync_flip=FALSE if radeon_present_screen_init sets
PresentCapabilityAsync, and the latter only sets it if the kernel driver
advertises support for async flips.
(Ported from radeon commit 1ca677309720e2f6c953c9e76f5b34c22a4416c6)
