dma-buf/sw_sync: Add fence deadline support
This consists of simply storing the most recent deadline, and adding an
ioctl to retrieve the deadline. This can be used in conjunction with
the SET_DEADLINE ioctl on a fence fd for testing. Ie. create various
sw_sync fences, merge them into a fence-array, set deadline on the
fence-array and confirm that it is propagated properly to each fence.
v2: Switch UABI to express deadline as u64
v3: More verbose UAPI docs, show how to convert from timespec
v4: Better comments, track the soonest deadline, as a normal fence
implementation would, return an error if no deadline set.
