[PATCH] vgacon: make VGA_MAP_MEM take size, remove extra use

VGA_MAP_MEM translates to ioremap() on some architectures.  It makes sense
to do this to vga_vram_base, because we're going to access memory between
vga_vram_base and vga_vram_end.

But it doesn't really make sense to map starting at vga_vram_end, because
we aren't going to access memory starting there.  On ia64, which always has
to be different, ioremapping vga_vram_end gives you something completely
incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being
nonsense.

As a bonus, we often know the size up front, so we can use ioremap()
correctly, rather than giving it a zero size.
