gma: Add option for VGA plane on the primary pipe

Add special VGA_PLANE_FRAMEBUFFER_OFFSET that, if set on the primary
pipe, toggles the use of the legacy VGA plane instead of the `hires`
plane.

The caller is responsible for the configuration of the VGA plane and
has to specify the framebuffer width and height accordingly.
