viafb: improve pitch handling

Split the pitch handling up and replaces the calculation from virtual xres
and bpp with fix.line_length which already contains the pitch and does not
add any constrains for the virtual resolution.

Also add a bit to the second pitch which the documentation mentions but
which was ignored by the driver.

Although it is a bit unclear what the right pitch for some LCD modes is
this patch should have no negative runtime impact.
