clk: qcom: gcc-glymur: Remove 85.71 MHz USB4 master clock frequency

The USB4 HPG says this frequency remains unused, remove it from the
frequency table to avoid any misunderstandings.

The reason it's unused seems to be that the lower RPMh level required
to support it (LOW_SVS) is not enough for other pieces of the pipeline
which require SVS, which in turn is enough to support a faster, 175-ish
MHz rate.
