wifi: rtw88: usb: Enable switching the RTL8814AU to USB 3

Browse Source 
The Realtek wifi 5 devices which support USB 3 are weird: when first
plugged in, they pretend to be USB 2. The driver needs to send some
commands to the device, which make it disappear and come back as a
USB 3 device.

The method used to switch the RTL8812AU also works for the RTL8814AU.
