misc/genalloc: Name subpools by of_node_full_name()
A previous commit tried to come up with more generic subpool names, but this isn't quite working: the node name was used elsewhere to match pools to consumers which regressed the nVidia Tegra 2/3 video decoder. Revert back to an earlier approach using of_node_full_name() instead of just the name to make sure the pool name is more unique, and change both sites using this in the kernel. It is not perfect since two SRAM nodes could have the same subpool name but it makes the situation better than before.
