[POWERPC] Added indirect_type to handle variants of PCI ops
The generic PCI config ops indirect support for ppc32 covers only two cases (implicit vs explicit) type 0/1 config cycles via set_cfg_type. Added a indirect_type bit mask to handle other variants. Added support for PCI-e extended registers and moved the cfg_type handling into the bit mask for ARCH=powerpc. We can also use this to handle indirect quirks.
