PCI/ASPM: Stop caching link L0s, L1 exit latencies
Previously we calculated the upstream and downstream L0s and L1 exit
latencies of the link in pcie_aspm_cap_init() and cached them in struct
pcie_link_state.latency_*.
These values are only used in pcie_aspm_check_latency() where they are
compared with the acceptable latencies on the link. This path is used when
removing or changing the D state of the device, so it's relatively low
frequency.
To reduce the amount of per-link data we store, remove the latency_*
entries from struct pcie_link_state and calculate the latencies directly
where they are needed.
