Bjorn Helgaas:
These would be material for a separate patch:

- The #defines for register offsets and bits are kind of a mess,
  e.g., PCIE_SMLH_LINKUP, PCIE_RDLH_LINKUP, PCIE_LINKUP,
  PCIE_L0S_ENTRY, and PCIE_LTSSM_STATUS_MASK are in
  PCIE_CLIENT_LTSSM_STATUS, but you couldn't tell that from the
  names, and they're not even defined together.

- Same for PCIE_RDLH_LINK_UP_CHGED, PCIE_LINK_REQ_RST_NOT_INT,
  PCIE_RDLH_LINK_UP_CHGED, which are in PCIE_CLIENT_INTR_STATUS_MISC.

- PCIE_LTSSM_ENABLE_ENHANCE is apparently in PCIE_CLIENT_HOT_RESET_CTRL?
  Sure wouldn't guess that from the names or the order of #defines.

- PCIE_CLIENT_GENERAL_DEBUG isn't used at all.

- Submissions based on the following v5 patches:
