reservation: cross-device reservation support, v4
This adds support for a generic reservations framework that can be
hooked up to ttm and dma-buf and allows easy sharing of reservations
across devices.
The idea is that a dma-buf and ttm object both will get a pointer
to a struct reservation_object, which has to be reserved before
anything is done with the contents of the dma-buf.
Changes since v1:
- Fix locking issue in ticket_reserve, which could cause mutex_unlock
to be called too many times.
Changes since v2:
- All fence related calls and members have been taken out for now,
what's left is the bare minimum to be useful for ttm locking conversion.
Changes since v3:
- Removed helper functions too. The documentation has an example
implementation for locking. With the move to ww_mutex there is no
need to have much logic any more.
