Currently pcibios_add_platform_entries() returns void, but could fail,
so instead have it return an int and propagate errors up to
pci_create_sysfs_dev_files().
Fixes:
arch/powerpc/kernel/pci_64.c: In function 'pcibios_add_platform_entries':
arch/powerpc/kernel/pci_64.c:878: warning: ignoring return value of
'device_create_file', declared with attribute warn_unused_result
arch/powerpc/kernel/pci_32.c: In function 'pcibios_add_platform_entries':
arch/powerpc/kernel/pci_32.c:1043: warning: ignoring return value of
'device_create_file', declared with attribute warn_unused_result
