phy: qcom: qmp-combo: Fix register base for QSERDES_DP_PHY_MODE

The register base that was used to write to the QSERDES_DP_PHY_MODE
register was 'dp_dp_phy' before commit 815891eee668 ("phy:
qcom-qmp-combo: Introduce orientation variable"). There isn't any
explanation in the commit why this is changed, so I suspect it was an
oversight or happened while being extracted from some other series.
Oddly the value being 0x4c or 0x5c doesn't seem to matter for me, so I
suspect this is dead code, but that can be fixed in another patch. It's
not good to write to the wrong register space, and maybe some other
version of this phy relies on this.
