[PATCH kernel v3 11/22] powerpc/pseries/npu: Enable platform support

[Alexey Kardashevskiy <aik@ozlabs.ru>]

We already changed NPU API for GPUs to not to call OPAL and the remaining
bit is initializing NPU structures.

This uses a new QEMU capability which marks NPU-enabled vPHBs as
"IBM,npu-vphb" and initializes an NPU structure per vPHB.
