dma-buf: Document DMA_BUF_IOCTL_SYNC (v3)
This adds a new "DMA Buffer ioctls" section to the dma-buf docs and adds
documentation for DMA_BUF_IOCTL_SYNC.
v2 (Daniel Vetter):
- Fix a couple typos
- Add commentary about synchronization with other devices
- Use item list format for describing flags
v3 (Pekka Paalanen):
- Clarify stalling requirements.
- Be more clear that that DMA_BUF_IOCTL_SYNC with SINC_END has to be
called before more GPU work happens.
