arm64: dts: renesas: r8a7795: sort subnodes of the root node

Sort subnodes of the root node alphanumerically.

This is part of an ongoing effort to provide consistent node

Also remove excessive line-wrapping of interrupts-extended property of
timer node.

This should not have any run-time effect.
