Florian Tobias Schandinat d60defb7b2 viafb: use more compact modesetting functions
This patch replaces the old timing setup code with a redesigned one.
The new code might be slightly faster as it has no conditinals and
does not write the same register multiple times. Also it makes the
comparison to the documentation easier.
Regressions are unlikely but could happen as a lot of hardware is
undocumented.

Florian Tobias Schandinat 936a3f770b viafb: improve pitch handling
This patch adds checks for minimum and maximum pitch size to prevent
invalid settings which could otherwise crash the machine. Also the
alignment is done in a slightly more readable way.

viafb: move some modesetting functions to a seperate file

This patch moves the modesetting functions which are already cleaned up
to a seperate file.
Just the beginning to bring some structure in this mess.
