[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.
