[PATCH 06/11] arm64: dts: renesas: r8a7796: move nodes which have no reg property out of bus

Move pmu_a5[73], timer and thermal-zones nodes from soc node to root node.
The nodes that have been moved do not have any register properties and thus
shouldn't be placed on the bus.

This problem is flagged by the compiler as follows:
