Merge branch 'pci/bwctrl'

- Add read/modify/write locking for Link Control 2, which is used to manage
  Link speed (Ilpo Järvinen)

- Cache all supported Link speeds for use by the PCIe bandwidth controller
  (Ilpo Järvinen)

- Extract the Link Bandwidth Management Status check into pcie_lbms_seen(),
  where it can be shared between the bandwidth controller and quirks that
  use it to help retrain failed links (Ilpo Järvinen)

- Re-add Link Bandwidth notification support with updates to address the
  reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen)

- Add pcie_set_target_speed() and related functionality to manage PCIe Link
  speed based on thermal constraints (Ilpo Järvinen)

- Add a thermal cooling driver to throttle PCIe Links via the existing
  thermal management framework (Ilpo Järvinen)

- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
  Järvinen)

- Drop duplicate pcie_get_speed_cap(), pcie_get_width_cap() declarations
  (Bjorn Helgaas)

* pci/bwctrl:
  PCI: Drop duplicate pcie_get_speed_cap(), pcie_get_width_cap() declarations
  selftests/pcie_bwctrl: Create selftests
  thermal: Add PCIe cooling driver
  PCI/bwctrl: Add pcie_set_target_speed() to set PCIe Link Speed
  PCI/bwctrl: Re-add BW notification portdrv as PCIe BW controller
  PCI: Abstract LBMS seen check into pcie_lbms_seen()
  PCI: Refactor pcie_update_link_speed()
  PCI: Store all PCIe Supported Link Speeds
  PCI: Protect Link Control 2 Register with RMW locking
  Documentation PCI: Reformat RMW ops documentation
