Subject: x86/PCI: Define to_pci_sysdata() even when !CONFIG_PCI
Git-commit: b9303bb1990950bd2f49ec1c85c015b5b6aac24b
Patch-mainline: v5.6-rc1
References: bsc#1175713

Recently, the to_pci_sysdata() helper was added inside the CONFIG_PCI
guard, but it is used inside a CONFIG_NUMA guard, which does not require
CONFIG_PCI.  This breaks builds on !CONFIG_PCI machines.  Make
to_pci_sysdata() available in all configurations.

Fixes: aad6aa0cd674 ("x86/PCI: Add to_pci_sysdata() helper")
