tridentfb: Blade3D clock fixes
This patch fixes following problems:
- does not allow the m parameter to reach 0 as
it locks the graphics core (power cycle needed)
- for the newer chips (with new clock registers)
does not allow of n / m ratio below 4 as it gives
unstable image on the Blade3D core
- extend shift parameter (k) range to 2 for the newer
chips to cope with the n /m >= 4 limit at low resolution
(bandwidth) modes
- prefer modes with higher n / m ratio (higher k values)
