board_inspector: maintain a mapping from cap names to cap struct

Browse Source 
In order to ease the access of certain capability structure of a PCI config
space, this patch changes the class PCIConfigSpace to maintain a
_caps_as_dict dictionary that maps capability names (as specified in the
caps.py and extcaps.py) to the actual capability structures.
