src/sb/intel/common/pirq_gen: Rework generating pin-route map

This creates a pin-route matrix first and then generates the ACPI
entries based on that. This approach has the advantage of being
simpler (no need for checks on double entries) and requiring less
access to the pci config space.

A few thing that are also fixed:
* Don't declare DEFAULT_RCBA redundantly.
* Only loop over PCI devices on bus 0
* Add a license header to rcba_pirq.c
* Remove inappropriate use of typedefs
