drm/mode: add the GTF algorithm in kernel space
Add the GTF algorithm in kernel space. And this function can be called to
generate the required modeline.
I copied it from the file of xserver/hw/xfree86/modes/xf86gtf.c. What I have
done is to translate it by using integer calculation. This is to avoid
the float-point calculation in kernel space.
At the same tie I also refer to the function of fb_get_mode in
drivers/video/fbmon.c
