On AMD Pink Sardine it's been observed that if another CM has run before the Linux CM that some registers may not match expectations which leads to a non-functional hotplug for PCIe devices.
Explicitly set these registers that have been observed to cause problems with hotplug to the defaults of the USB4 spec.
Mario Limonciello (2): thunderbolt: Explicitly reset plug events delay back to USB4 spec value thunderbolt: Explicitly enable lane adapter hotplug events at startup
