vga-switcheroo: Remove unused interfaces

Remove all unused interfaces that used to implement the functionality
of pre_switch and post_switch.

For pre_switch, remove vga_switcheroo_client_fb_set(). This further
allows for removing all symbols and data structures that refer to
fbdev; such as fb_info and fb_switch_outputs().

For post_switch, remove the reprobe callback from the client ops.

v2:
- move changes to fbcon and drivers into other patches
