vga: dont confuse io bar with mem bar in vgas3 and vgavesa
...
harmless bug. just make sure we loop over the memory
bars only and skip the io bars.

vga: softscreen
...
allow the shadow framebuffer (softscreen) to be used with any
vga driver, not just vesa. this removes the ugly scr->paddr = 0
hack employed by vesa driver to force softscreen and adds a
softscreen vgactl message that can switch the feature on and off
at runtime.
softscreen can greatly improve graphics performance when bus
reads are slow even tho it disables hardware acceleration.
