Previously we calculated the device's acceptable L0s and L1 exit latencies in pcie_aspm_cap_init() and cached them in struct pcie_link_state. These values are only used in pcie_aspm_check_latency() where they are compared with the actual exit latencies of 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 acceptable[] arrays from struct pcie_link_state and calculate them directly from the already-cached Device Capabilities register when needed.
