For optimus and powerxpress muxless we really want the GPU driver deciding when to power up/down the GPU, not userspace. This adds the ability for a driver to dynamically power up/down the GPU and remove the switcheroo from controlling it, the switcheroo reports the dynamic state to userspace also. It also adds 2 power domains, one for machine where the power switch is controlled outside the GPU D3 state, so the powerdown ordering is done correctly, and the second for the hdmi audio device to make sure it can resume for PCI config space accesses. v1.1: fix build with switcheroo off v2: add power domain support for radeon and v1 nvidia dsms v2.1: fix typo in off case v3: add audio power domain for hdmi audio + misc audio fixes v4: use PCI_SLOT macro, drop power reference on hdmi audio resume failure also.
