Syncpoints don't need to be associated with any client,
so remove the property, and expose host1x_syncpt_alloc.
This will allow allocating syncpoints without prior knowledge
of the engine that it will be used with.

* Clean up host1x_syncpt_alloc signature to allow specifying
a name for the syncpoint.
* Export the function.

If we expose it publicly, it's a good idea to add kerneldoc.
Will fix.

I know this just keeps with the status quo, but I wonder if we should
change this to be just "%u" if name == NULL to avoid a weird-looking
name. Or perhaps we want to enforce name != NULL by failing if that's
not the case?
I'll see about making the name mandatory.
