Instances of fbcon use a number callbacks to support tile-based
drawing or console rotation. The fields are writeable in struct
fbcon_ops. Each case; unrotated, various rotated and tile-based
drawing; uses a set of related calbacks. Updating these 'bitops'
at runtime is spread throughout various helper functions.

This series puts related callbacks into dedicated instances of the
new type struct fbcon_bitops. Changing the callbacks at runtime
then only requires to pick the correct instance. It further allows
the various struct fbcon_bitops' to be declared 'static const', which
makes them write-protected at runtime.

Makes the fbcon bitops easier and safer to use and modify.

  fbcon: Rename struct fbcon_ops to struct fbcon
  fbcon: Set rotate_font callback with related callbacks
  fbcon: Move fbcon callbacks into struct fbcon_bitops
  fbcon: Streamline setting rotated/unrotated bitops
  fbcon: Pass struct fbcon to callbacks in struct fbcon_bitops
