Subject: [PATCH] arm64: dts: qcom: qcs6490-rb3gen2: Use 'edp_hot' function for hpd gpio

Currently, hpd gpio is configured as a general-purpose gpio, which does
not support interrupt generation. This change removes the generic
hpd-gpios property and assigns the edp_hot function to the pin,
enabling proper irq support.

Fixes: 756efb7cb7293 ("arm64: dts: qcom: qcs6490-rb3gen2: Add DP output")
