ALSA: hda - Fix uninitialized HDMI controllers with VGA-switcheroo
When VGA-switcheroo is built in but unused on systems with multiple graphics cards, the initializations of non-default graphics cards are skipped and never enabled (because the switcheroo is activated only when the controller supports). The current behavior is for avoiding the system lockup by accessing the disabled GPU, but due to the recent change in VGA-switcheroo, it determines the state simply by checking with the default VGA device. This is the culprit. Now with the new vga_switcheroo_get_client_state(), we can know the initial state of the bound GPU, thus can determine the initial audio client state more correctly.
