[PATCH kernel v3 11/22] powerpc/pseries/npu: Enable platform support
From: Alexey Kardashevskiy <hidden>

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.
