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.
