Subject: [PATCH 2/5] lspci: Fully decode ASPM support from Link Capabilities

The ASPM Support field in Link Capabilities is two bits, and all four
possible encodings are defined as of PCIe spec r3.0.  Previously, lspci
only decoded values 1, 2, and 3.  This adds 0, so lspci will show "ASPM
not supported" instead of "ASPM unknown".
