vga: cleanup mapping of VRAM for non-PCI VGA
vga_init_vbe is now used only from ISA VGA cards. Since the alias is
not needed anymore, remove it (effectively reverting commit 8294a64d7f,
"vga: fix vram double-mapping with -vga std and -M pc-0.12", 2012-05-29)
and the now unused vbe_mapped field of VGACommonState. The function now
consists of a single memory_region_add_subregion call, so we can inline
it; this avoids incorrect usage from PCI cards.
