[PATCH v2] x86/PCI: ensure to_pci_sysdata usage is available to !CONFIG_PCI

["Jason A. Donenfeld" <Jason@zx2c4.com>]

Recently, the helper to_pci_sysdata was added inside of the CONFIG_PCI
guard, but it is used from inside of a CONFIG_NUMA guard, which does not
require CONFIG_PCI. This breaks builds on !CONFIG_PCI machines. This
commit makes that function available in all configurations.
