[PATCH] arm64: dts: rockchip: Add Rotation Property for OGA Panel

From: Chris Morgan <redacted>

Add rotation property for Odroid Go Advance panel to note that it is
rotated 270 degrees. Rotation affects DRM connector after this patch:

https://cgit.freedesktop.org/drm/drm/commit/drivers/gpu/drm/panel/panel-elida-kd35t133.c?id=610d9c311b1387f8c4ac602fee1f2a1cb0508707

Note: following example of motorola-mapphone-common and
tegra30-asus-nexus7-grouper-common where rotation is specified by
itself with other physical properties (which are already hard-coded
into the driver in this case so not necessary). Please advise if this
is not the correct manner in the devicetree to specify this.
