mb/google/eve: Enable HotPlug on PCIe root port for WiFi

Enable HotPlug for the PCIe root port that the WiFi device
is on so the OS can re-train the link without needing a reboot
if it goes down unexpectedly at runtime.

BUG=b:72417777
TEST=enable HotPlug on Eve Root Port 0 (WiFi) and check in
linux that it is identified as a HotPlug capable root port.
