Runtime PM enabled USB port no longer responses to hotplug after commit dec08194ff

Hi,

My ASUS PRIME B350M-A uses this XHCI chip:

03:00.0 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] USB
3.1 XHCI Controller [1022:43bb] (rev 02)

...which matches to the PCI_DEVICE_ID_AMD_PROMONTORYA_2.

Revert commit dec08194ffeccfa1cf085906b53d301930eae18f ("xhci: Limit
USB2 port wake support for AMD Promontory hosts") can solve the
regression.

Now both front panel USB ports stop responding to hotplug events now.
Is it an overkill to disable all wake up bits?

Thanks.
