phy: qcom: qmp-combo: fix sm8650 voltage swing table

The QMP USB3/DP PHY found in the SM8650 SoC requires a slightly
different Voltage Swing table for HBR/RBR link speeds.

Add a new hbr/rbr voltage switch table named "v6" used in a new
sm8650 qmp_phy_cfg struct replacing the sm8550 fallback used for
the sm8650 compatible.
