7334128a2e pci_decode: export prefetchable attribute of BARs
Memory descriptors in PCI BARs have a prefetchable bit, which can
be used to optimize memory access when setting, e.g. write-combined
in page-table entries.

2cc6c1adef pci: export BAR indices, sub-vendor, -product, rev
The pci_decode has to extract the additional fields from the PCI configuration
space. The platform driver again has to parse and forward the knowledge too.
The PCI BAR indices are exported when info="yes" is set in the policy node for
the corresponding session.

5bf3e72d37 pci: return correct I/O port base from BAR
The base address of I/O ports has a different encoding than
those of I/O memory. This needs to be encountered in the PCI
config helper utilities.

cacb6136fa app/pci_decode: prepare pci device information
To discharge the generic platform driver from certain PCI bus scanning,
and ACPI + kernel specifics, this commit introduces a new component,
which consumes the acpi drivers report and the platform_info from core
to prepare a devices ROM for the platform driver that contains all
PCI devices and its resources.
