video: tegra: host: New submit interface
Add new interface for submit. Now a single IOCTL will send the whole
job to kernel.
Also removes 32 sync point limit from the interface, and adds
possibility to have variable number of sync point ids and increments.
Because of these changes, nvhost_job has been refactored to remove
dependency to the submit header struct.
