dmaengine: rcar-dmac: Add Renesas R-Car Gen2 DMA Controller (DMAC) driver The DMAC is a general purpose multi-channel DMA controller that supports both slave and memcpy transfers. The driver currently supports the DMAC found in the r8a7790 and r8a7791 SoCs. Support for compatible DMA controllers (such as the audio DMAC) will be added later. Feature-wise, automatic hardware handling of descriptors chains isn't supported yet. LPAE support is implemented.

config SH_DMAE_BASE
bool "Renesas SuperH DMA Engine support"
dmaengine: sh: Remove R-Mobile APE6 support Renesas R-Mobile APE6 support is currently unused: - DMA slaves were never enabled in r8a73a4.dtsi, - The driver relies on legacy filter matching and describing all slaves and MID/RIDs in a table, unlike modern DMA engine drivers for similar hardware like rcar-dmac, - The driver doesn't seem to work well. Remove the driver, it can be resurrected from git history when needed. As this was the last user of SH_DMAE_BASE on Renesas ARM SoCs, the sh-dma-engine driver core is now used on SuperH only. Note that the DT bindings are still present, as r8a73a4.dtsi uses them.
