Kenji Kaneshige 07d92760d2 PCI ASPM: introduce capable flag
Introduce 'aspm_capable' field to maintain the capable ASPM setting of
the link. By the 'aspm_capable', we don't need to recheck latency
every time ASPM policy is changed.

Each bit in 'aspm_capable' is associated to ASPM state (L0S/L1). The
bit is set if the associated ASPM state is supported by the link and
it satisfies the latency requirement (i.e. exit latency < endpoint
acceptable latency). The 'aspm_capable' is updated when

  - an endpoint device is added (boot time or hot-plug time)
  - an endpoint device is removed (hot-unplug time)
  - PCI power state is changed.
