The i.MX95 USB3.0 PHY supports XTAL 24MHz clock by default as reference
clock and 100MHz clock as alternate reference clock. If the default
reference clock brings USB performance degradation in bad condition, such
as the working temperature is too low or too high, switch to alternate
clock may overcome the degradation. This will add alternate clock support
to enhance the function of USB3.0 PHY.
