[PATCH] vgaarb: Call vga_arb_device_init() after PCI enumeration

[Huacai Chen]

We should call vga_arb_device_init() after PCI enumeration, otherwise it
may fail to select the default VGA device. Since vga_arb_device_init()
and PCI enumeration function (i.e., pcibios_init() or acpi_init()) are
both wrapped by subsys_initcall(), their sequence is not assured. So, we
use subsys_initcall_sync() instead of subsys_initcall() to wrap vga_arb_
device_init().
