Depending on rotation settings, fbcon sets different callback functions in struct fbcon_par from within fbcon_set_bitops(). Declare the callback functions in the new type struct fbcon_bitops. Then only replace the single bitops pointer in struct fbcon_par. Keeping callbacks in constant instances of struct fbcon_bitops makes it harder to exploit the callbacks. Also makes the code slightly easier to maintain. For tile-based consoles, there's a separate instance of the bitops structure.
