video: tegra: host: implement dynamic synpt
- implement dynamic syncpoint assignment framework
- provide API nvhost_get_syncpt_client_managed() to get client managed
syncpt which is requested by display, avp, and tegra_camera drivers
- provide API nvhost_get_syncpt_host_managed() for host managed syncpts
- this API is used by host1x clients and gpu
- provide API nvhost_free_syncpt() to free a syncpt
- both client managed and host managed APIs call nvhost_get_syncpt() to
find a free syncpt and reserve it
- remove static syncpt mappings from nvhost_device_data of all clients
- keep VBLANK syncpts hard-coded until we resolve the conflicts with
hard coded syncpt increments from bootloader
