vgabios: implement AX=1120H..1124H functions

These function only have to set INT 1Fh and INT 43h, and set
the BDA height + number of rows.

I could not find out whether AX=1120h should also set the character
height to 8.  I think not, because INT 43h might still point to
14- or 16-pixel high characters and in this case INT 1Fh will not
be used at all.
