PCI/VGA: Move vgaarb to drivers/pci
The VGA arbiter is really PCI-specific and doesn't depend on any GPU
things. Move it to the PCI subsystem.
Note that misc_init() must be called before vga_arb_device_init(). These
are both subsys_initcalls, so this ordering depends on the link order,
which is determined by drivers/Makefile:
obj-y += pci/
obj-y += char/ <-- misc_init()
obj-y += gpu/ <-- vga_arb_device_init() (before this commit)
The drivers/pci/ subsys_initcalls are called *before* misc_init(), so
convert vga_arb_device_init() to subsys_initcall_sync(), which is called
after *all* subsys_initcalls.
