[PATCH v2 11/11] arm64: dts: qcom: sdm845-google-crosshatch: Add display panel

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

From: David Heidelberg <david@ixit.cz>

Wire up the Samsung AMB630QY01 AMOLED panel on the Pixel 3 XL and drop
the MDSS/DISPCC disables that kept simple-framebuffer alive.
