gpu: host1x: Support for syncpoint pools

Browse Source 
Add support for syncpoint pools. These are configuration-dependent
subsets of syncpoints that can only be allocated by specifying
an allocation specifically from that pool.

In this patch, we add support for the GPU pool. On certain systems,
the GPU is for safety purposes limited to accessing a specific set
of syncpoints. Therefore, syncpoints allocated for GPU use need to
come from this pool.
