fix(DisplayDeviceTreeHelperLib): avoid using DeviceTreeHelperLib

Do not use DeviceTreeCheckNodeSingleCompatibility when searching for
simple-framebuffer DT nodes. This function requires the nodes' status to
be "okay", but simple-framebuffer nodes are intentionally disabled; UEFI
should enable them when display is up.
