Manivannan Sadhasivam 52ec1cae52 PCI: pciehp: Add Qualcomm quirk for Command Completed erratum 
[ Upstream commit 82b34b0800 ]

The Qualcomm PCI bridge device (Device ID 0x010e) found in chipsets such as
SC8280XP used in Lenovo Thinkpad X13s, does not set the Command Completed
bit unless writes to the Slot Command register change "Control" bits.

This results in timeouts like below during boot and resume from suspend:

  pcieport 0002:00:00.0: pciehp: Timeout on hotplug command 0x03c0 (issued 2020 msec ago)
  ...
  pcieport 0002:00:00.0: pciehp: Timeout on hotplug command 0x13f1 (issued 107724 msec ago)

Add the device to the Command Completed quirk to mark commands "completed"
immediately unless they change the "Control" bits.
