PCI: Disable completion timeout
For PCIe devices, there are 2 bits used to control completion
timeout as follows:
PCIe Cap + 0x24, Device Capabilities 2 Register, bit#4
PCIe Cap + 0x28, Device Control 2 Register, bit#4
The patch adds function pci_disable_completion_timeout(), which
is called during bootup or after PE reset.
It's responsing to bug#114961
