Subject: [PATCH -next] drm/amdkfd: Fix -Wunused-const-variable warning

If KFD_SUPPORT_IOMMU_V2 is not set, gcc warns:

drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_device.c:121:37: warning: ‘raven_device_info’ defined but not used [-Wunused-const-variable=]
 static const struct kfd_device_info raven_device_info = {
                                     ^~~~~~~~~~~~~~~~~

Move it to ifdef block.
