powerpc: Introduce ppc_pci_flags accessors
Currently there are a number of platforms that open code access to
the ppc_pci_flags global variable. However, that variable is not
present if CONFIG_PCI is not set, which can lead to a build break.
This introduces a number of accessor functions that are defined
to be empty in the case of CONFIG_PCI being disabled. The
various platform files in the kernel are updated to use these.
