[PATCH] phy: qcom: qmp-combo: fix VCO div offset on v5_5nm and v6

[Johan Hovold]

Commit 5abed58a8bde ("phy: qcom: qmp-combo: Fix VCO div offset on v3")
fixed a regression introduced in 6.5 by making sure that the correct
offset is used for the DP_PHY_VCO_DIV register on v3 hardware.

Unfortunately, that fix instead broke DisplayPort on v5_5nm and v6
hardware as it failed to add the corresponding offsets also to those
register tables.

Thanks! I didn't know the qmp_v4_configure_dp_phy() function was used by
v5 or v6, but upon further inspection that seems to be the case. Maybe
that should be renamed to qmp_v456_configure_dp_phy() to match and then
qmp_v456_configure_dp_phy() get inlined into qmp_v4_configure_dp_phy().
Either way:
