This series add some missing support for USB 3.2 SuperSpeed Plus detection on
the host side. A SuperSpeed Plus device can operate in gen2x2, gen2x1, or
gen1x2. The current implementation can't detect whether the device is in Gen 1
or Gen 2 speed. We can do this by matching for the lane speed exponent and
mantissa of the SSP sublink speed capability descriptor from the hub driver.

Also, the current xHCI driver is missing some reports for the default SSP
Sublink Speed capability for USB 3.2 roothub. This series also add some support
for xHCI driver detecting various SuperSpeed Plus GenXxY.

I took the first 4 patches already and will wait for Mathias to review
the rest.

thanks,
