Subject: [PATCH v4 02/13] phy: qcom: qmp-usbc: Rename USB-specific ops to
prepare for DP support
To support following DisplayPort (DP) mode over the Type-C PHY, rename
USB-specific functions and ops to clearly separate them from common or
DP-related logic.
This is a preparatory cleanup to enable USB + DP dual mode.
