vgabios: Split vgafb_scroll() into separate move and clear functions. Rewrite the low-level scroll code so that it is implemented using two basic operations: move text and clear text. This simplifies the low-level code as it no longer needs to handle up scrolling vs down scrolling. Determining the direction of the scroll is now done in the higher level (vgabios.c) code.
