phy: qcom: qmp-usbc: Add DP-related fields for USB/DP switchable PHY

Browse Source 
Extend qmp_usbc_offsets and qmp_phy_cfg with DP-specific fields,
including register offsets, init tables, and callback hooks. Also
update qmp_usbc struct to track DP-related resources and state.
This enables support for USB/DP switchable Type-C PHYs that operate
in either mode.
