Fix the pl330 main and queue vmstate description.
There were missing POINTER flags causing crashes during
incoming migration because:
+ PL330State chan field is a pointer to an array
+ PL330Queue queue field is a pointer to an array
Also bump corresponding vmsd version numbers.

I found this while working on reset with xilinx-zynq machine.
I'm not sure what's the vmsd version policy in such cases (for
backward compatibility). I've simply bumped them since migration
was not working anyway (vmstate_load_state was erasing critical part
of PL330State and causing segfaults while loading following fields).
Tested doing migration with the xilinx-zynq-a9 machine.
