vga_switcheroo: Add pre_switch callback to client ops

Browse source

Add pre_switch to struct vga_switcheroo_client_ops to inform the
switcheroo client about upcoming switches of the outputs.

This callback is intended to replace the hard-coded call to fbdev's
fb_switch_outputs(). With DRM supporting more clients than just fbdev
emulation, something more flexible is required.

v2:
- remove non-sensical gpu_bound documentation (Sashiko)
