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.
