drm/amdgpu: Fix NULL pointer when load kfd driver with PP block is disabled
When PP block is disabled, return a fix value(100M) for mclk and sclk on bare-metal mode. This will cover the emulation mode as well. Signed-off-by: Shaoyun Liu <Shaoyun.Liu@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
