PCI/ASPM: Remove struct aspm_register_info.l1ss_cap_ptr
Save the L1 Substates Capability pointer in struct pci_dev. Then we don't
have to keep track of it in the struct aspm_register_info and struct
pcie_link_state, which makes the code easier to read. No functional change
intended.
[bhelgaas: split to a separate patch]
