ARM: dts: r8a7745: Add sound support

Define the generic r8a7745(RZ/G1E) part of the sound device node.

This patch is based on the r8a7794 sound work by Sergei Shtylyov.

(cherry picked from commit 17d2e479d09e597c9915f0ab853edfa8f5010476)
(modified clocks and power-domains properties. Removed resets and
reset-names properties. Also changed rcar_sound,module children names
(e.g. from ssi-0 to ssi@0) to make them similar to other R-Car Gen2
devices in 4.4)
