x86/Sandy Bridge: Sandy Bridge workaround depends on CONFIG_PCI
commit e43b3cec711a61edf047adf6204d542f3a659ef8 upstream. early_pci_allowed() and read_pci_config_16() are only available if CONFIG_PCI is defined. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Abdallah Chatila <abdallah.chatila@ericsson.com>
