Alistair Popple a1409adac7 powerpc/powernv/npu: Prevent overwriting of pnv_npu2_init_contex() callback parameters ...

There is a single npu context per set of callback parameters. Callers
should be prevented from overwriting existing callback values so
instead return an error if different parameters are passed.
