Some peripherals on RZ/G3E SoCs (SSIU, SPDIF, SCU/SRC, DVC) require explicit ACK signal routing through the ICU via the ICU_DMACKSELk registers for level-based DMA handshaking. Add rzv2h_icu_register_dma_ack() to configure ICU_DMACKSELk, routing a DMAC channel's ACK signal to the specified peripheral.
