FROMLIST: arm64: dts: qcom: qcs6490-rb3gen2: use DP controller native HPD

The base device tree configures the edp_hot_plug_det pin using the
"edp_hot" function on GPIO 60. However, on qcs6490-rb3gen2 this external
HPD GPIO does not generate a connect event when a display is already
connected at boot, causing the DP/eDP display to remain disabled.

The DP controller’s native HPD correctly detects the connected sink
in this scenario, so continue using the DP controller native HPD
on the qcs6490-rb3gen2 platform instead of the external HPD GPIO.
