This makes it easier to disable it in production kernels if this new feature causes problems in production environments.

drm/amdkfd: Enable userptr support when KFD is enabled ROCm user mode depends on userptr support. Without it, KFD is basically useless. Make sure HSA_AMD selects the same options as DRM_AMDGPU_USERPTR to avoid broken configurations where userptr gets enabled but its dependencies are disabled.
