[PATCH] phy: qcom: qmp-combo: update offsets table for x1e80100

[Tapas Rana]

x1e80100_usb3dpphy_cfg uses qmp_v6_n4_usb3phy_regs_layout, which
places QPHY_PCS_CLAMP_ENABLE in the PCS_AON register space. However,
it uses qmp_combo_offsets_v5 currently, which does not define the
usb3_pcs_aon region. As a result, qmp->pcs_aon is not mapped and
autonomous mode falls back to pcs_misc for clamp control.

Add a dedicated USB3+DP V6 offsets table with usb3_pcs_aon included
and use it for x1e80100_usb3dpphy_cfg so clamp control is performed
through the correct PCS_AON register space.
