[PATCH] Update cyblafb driver

This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.

Main advantages:
============
  - vxres > xres support
  - ywrap and xpan support
  - much faster for almost all modes (e.g. 1280x1024-16bpp
     draws more than 41 full screens of text instead of about 25
     full screens of text per second on authors Epia 5000)
  - module init/exit code fixed
  - bugs triggered by console rotation fixed
  - lots of minor improvements
  - startup modes suitable for high performance scrolling
     in all directions

This diff  also contains a lot of white space fixes.

No side effects are possible, only one single graphics core is affected.

+
+      - the vesafb parameter has been removed as I decided to allow the
+        feature without any special parameter.
+
+      - Cyblafb does not use the vga style of panning any longer, now the
+        "right view" register in the graphics engine IO space is used. Without
+        that change it was impossible to use all available memory, and without
+        access to all available memory it is impossible to ywrap.
+
+      - The imageblit function now uses hardware acceleration for all font
+        widths. Hardware blitting across pixel column 2048 is broken in the
+        cyberblade/i1 graphics core, but we work around that hardware bug.
+
+      - modes with vxres != xres are supported now.
+
+      - ywrap scrolling is supported now and the default. This is a big
+        performance gain.
+
+      - default video modes use vyres > yres and vxres > xres to allow
+        almost optimal scrolling speed for normal and rotated screens
+
+      - some features mainly usefull for debugging the upper layers of the
+        framebuffer system have been added, have a look at the code
+
+      - fixed: Oops after unloading cyblafb when reading /proc/io*
+
+      - we work around some bugs of the higher framebuffer layers.
