Subject: [PATCH] arm64: dts: qcom: sc8280xp-x13s: Use the correct DP PHY
 compatible

The DP PHY needs different settings when an eDP display is used.
Make sure these apply on the X13s.

FWIW
I could not notice any user-facing change stemming from this commit.

Fixes: f48c70b111b4 ("arm64: dts: qcom: sc8280xp-x13s: enable eDP display")
Signed-off-by: Konrad Dybcio <konrad.dybcio@...aro.org>

I have no idea whether DP3 is hardwired to be eDP, like it
seems to be on the last DP controller of SC7280. In that
case this would be moved to the SoC DTSI.
