Pull pci updates from Bjorn Helgaas:
 "Enumeration:
   - Move the VGA arbiter from drivers/gpu to drivers/pci because it's
     PCI-specific, not GPU-specific (Bjorn Helgaas)
   - Select the default VGA device consistently whether it's enumerated
     before or after VGA arbiter init, which fixes arches that enumerate
     PCI devices late (Huacai Chen)

  Resource management:
   - Support BAR sizes up to 8TB (Dongdong Liu)

  PCIe native device hotplug:
   - Fix "Command Completed" tracking to avoid spurious timouts when
     powering off empty slots (Liguang Zhang)
   - Quirk Qualcomm devices that don't implement Command Completed
     correctly, again to avoid spurious timeouts (Manivannan Sadhasivam)

  Peer-to-peer DMA:
   - Add Intel 3rd Gen Intel Xeon Scalable Processors to whitelist
     (Michael J. Ruhl)

  APM X-Gene PCIe controller driver:
   - Revert generic DT parsing changes that broke some machines in the
     field (Marc Zyngier)

  Freescale i.MX6 PCIe controller driver:
   - Allow controller probe to succeed even when no devices currently
     present to allow hot-add later (Fabio Estevam)
   - Enable power management on i.MX6QP (Richard Zhu)
   - Assert CLKREQ# on i.MX8MM so enumeration doesn't hang when no
     device is connected (Richard Zhu)

  Marvell Aardvark PCIe controller driver:
   - Fix MSI and MSI-X support (Marek Behún, Pali Rohár)
   - Add support for ERR and PME interrupts (Pali Rohár)

  Marvell MVEBU PCIe controller driver:
   - Add DT binding and support for "num-lanes" (Pali Rohár)
   - Add support for INTx interrupts (Pali Rohár)

  Microsoft Hyper-V host bridge driver:
   - Avoid unnecessary hypercalls when unmasking IRQs on ARM64 (Boqun
     Feng)

  Qualcomm PCIe controller driver:
   - Add SM8450 DT binding and driver support (Dmitry Baryshkov)

  Renesas R-Car PCIe controller driver:
   - Help the controller get to the L1 state since the hardware can't do
     it on its own (Marek Vasut)
   - Return PCI_ERROR_RESPONSE (~0) for reads that fail on PCIe (Marek
     Vasut)

  SiFive FU740 PCIe controller driver:
   - Drop redundant '-gpios' from DT GPIO lookup (Ben Dooks)
   - Force 2.5GT/s for initial device probe (Ben Dooks)

  Socionext UniPhier Pro5 controller driver:
   - Add NX1 DT binding and driver support (Kunihiko Hayashi)

  Synopsys DesignWare PCIe controller driver:
   - Restore MSI configuration so MSI works after resume (Jisheng
     Zhang)"
