fbdev: remove cyblafb driver
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).
