Subject: [PATCH 2/2] arm64: dts: sc8280xp-x13s: fix external display 'data-lanes'

The 'data-lanes' property belongs in the controller node but was
erroneously moved to the endpoint nodes in the last revision of the
external display series:

	[drm] Invalid property "data-lanes", default max DP lanes = 4

Fixes: 8fcff430faee ("arm64: dts: qcom: sc8280xp-x13s: Enable external display")
