drm/radeon: fix runpm handling on APUs (v4)
Don't try and runtime suspend the APU in PX systems. We only want to power down the dGPU. v2: fix harder v3: fix stupid typo v4: consolidate runpm enablement to a single flag bugs: https://bugs.freedesktop.org/show_bug.cgi?id=75127 https://bugzilla.kernel.org/show_bug.cgi?id=72701 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
