dts: update to v4.16-rc1
Also includeded: ARM: dts: am33xx: do not delete no longer existing clocks Several clocks are removed from the am33xx dts files with v4.16-rc1. Remove the corresponding /delete-node/ directives aswell to avoid dtc breakage. Also included: ARM: dts: imx6qdl: SolidRun: Fix upstream include Upstream dts file way renamed, so change include name accordingly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
