[PATCH 1/8] drm/fbdev-helper: Do delayed switcheroo in lastclose helper

[Thomas Zimmermann <tzimmermann@suse.de>]

Amdgpu and nouveau call vga_switcheroo_process_delayed_switch() from
their lastclose callbacks. Call it from the fbdev lastclose helper,
so that the driver functions can finally be removed.

The fbdev call is part of all lastclose handling that restores the
DRM fbcon terminal. Only PCI devices with enabled switcheroo do the
delayed switching. The call has no effect on other drivers.
