Takashi Iwai fcd90d7dea vga_switcheroo: Fix missing gpu_bound call at audio client registration 
commit fc09ab7a767394f9ecdad84ea6e85d68b83c8e21 upstream.

The commit 37a3a98ef6 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound.  The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound.  When an audio client is registered
after that point, it would miss the gpu_bound call.  This leads to the
unexpected lack of runtime PM in HD-audio side.

For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.
