wifi: rtw88: usb: Support USB 3 with RTL8822CU/RTL8822BU
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.
Implement the required commands in rtw88.
When a USB 3 device is plugged into a USB 2 port, rtw88 will try to
switch it to USB 3 mode only once. The device will disappear and come
back still in USB 2 mode, of course.
Some people experience heavy interference in the 2.4 GHz band in
USB 3 mode, so add a module parameter switch_usb_mode with the
default value 1 to let people disable the switching.
