fbdev: remove cyblafb driver

Browse source 
A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.

Changes to the tridentfb driver:

- FBINFO_READS_FAST added to the tridentfb.  The cyblafb used a blitter
  for scrolling which is faster than color expansion on Cyberblade
  chipsets.  The blitter is slower on a discrete Blade3D core.  Use the
  blitter for scrolling in the tridentfb only for integrated Blade3D
  cores.  Now, scrolling speed is about equal for the tridentfb and the
  cyblafb.

- a copyright notice addition is done on request of Jani Monoses (the
  first author of the tridentfb).

Tested on AGP Blade3D card and PCChips
M787CLR motherboard: VIA C3 cpu +
VT8601 north  bridge (aka Cyberblade/i1).

This driver is supposed to support the Trident Cyberblade/i1
graphics core integrated in the VIA VT8601A North Bridge,
also known as VIA Apollo PLE133.
Status:
- Developed, tested and working on EPIA 5000 and EPIA 800.
- Does work reliable on all systems with CRT/LCD connected to
normal VGA ports.
- Should work on systems that do use the internal LCD port, but
this is absolutely not tested.
Character imageblit, copyarea and rectangle fill are hw accelerated,
ypan scrolling is used by default.
Please do read <file:Documentation/fb/cyblafb/*>.
To compile this driver as a module, choose M here: the
module will be called cyblafb.

There are also integrated versions of these chips called CyberXXXX,
CyberImage or CyberBlade. These chips are mostly found in laptops
but also on some motherboards. For more information, read
<file:Documentation/fb/tridentfb.txt>
but also on some motherboards including early VIA EPIA motherboards.

Say Y if you have such a graphics board.
