Add support for inserting syncpoint waits in the CDMA pushbuffer.
These waits need to be done in HOST1X class, while gather submitted
by the application execute in engine class.
Support is added by converting the gather list of job into a command
list that can include both gathers and waits. When the job is
submitted, these commands are pushed as the appropriate opcodes
on the CDMA pushbuffer.
Also supported are waits relative to the start of the job,
which are useful for jobs doing multiple things with an engine
that doesn't natively support pipelining.
While at it, use 32-bit waits on chips that support them.

The host1x unit found in Tegra210 SoCs is very similar to the unit in
Tegra124, but it has 2 additional channels for a total of 14 channels.
