[PATCH/v2] Atari frame buffer fixes

[Geert Uytterhoeven]

This patchsets contains several fixes for the Atari frame buffer device, and
includes a refactoring of the c2p (Chunky-to-Planar) code:
  [1] fbdev: atafb - Fix line length handling
  [2] fbdev: atafb - Fix 16 bpp console
  [3] fbdev: c2p - Correct indentation
  [4] fbdev: c2p - Cleanups
  [5] fbdev: c2p - Extract common c2p core to c2p_core.h
  [6] fbdev: c2p/atafb - Add support for Atari interleaved bitplanes
  [7] fbdev: c2p - Rename c2p to c2p_planar

Changes since previous submission:
  - Convert macros to static inline functions
  - Make sure we get a build-time error (undefined reference to
    'c2p_unsupported') in case of future misuse
  - Replace `unsigned long' by `u32' in comp(), as that's what all callers use
  - Use {get,put}_unaligned_be32() in store_{iplan2,planar}{,_masked}()

If nobody objects, I'd like to push this to Linus via the m68k tree, as the
c2p code is used by m68k drivers (atafb and amifb) only.
