video: tegra: host: Refactor context handling logic
Currently nvhost hard codes usage of context handler and sync point
id. Split the context handler and context structures into generic and
host1x specific parts, and move the allocation to happen via a
function pointer in nvhost_device.
Also updates gr3d and mpe to use sync point id and waitbase from
nvhost_device.
