x86/platform/uv: Make SGI UV dependent on CONFIG_PCI 

Recent PCI changes stopped exporting PCI constants if !CONFIG_PCI,
which made the UV build fail:

  arch/x86/kernel/apic/x2apic_uv_x.c:843:16: error: ‘PCI_VGA_STATE_CHANGE_BRIDGE’ undeclared (first use in this function)
  arch/x86/kernel/apic/x2apic_uv_x.c:1023:2: error: implicit declaration of function ‘pci_register_set_vga_state’ [-Werror=implicit-function-declaration]

As it's unlikely that an UV bootup will get far without PCI
enumeration, make the platform Kconfig switch (CONFIG_X86_UV)
depend on CONFIG_PCI=y.

This option is needed in order to support SGI Ultraviolet systems.
If you don't have one of these, you should say N here.
