According to user reference manual for R-CAR H3, M3-W and M3-N SoCs,
in order to access busif4 ~ busif7, extended audio dmac registers
(PDMASAREn, PDMADAREn, PDMACHCREn)
need to be used, rather than basic audio dmac registers
(PDMASARn, PDMADARn, PDMACHCRn)

Now DT bindings has stated that extended Audio dmac register set need
to be used when available with patch
https://patchwork.kernel.org/patch/10856905/

This patch set updates H3 (= r8a7795), M3-W (= r8a7796) and M3-N (=r8a77965)
to use extended audio dmac register set.

---
v4: use a single patch to update

v3: update H3 (= r8a7795), M3-W (= r8a7796) and M3-N (=r8a77965) to point
    point to extended audio dmac register set in DT

v2: update rsnd driver to use extended register set when available
    rename R-CAR E3 audio dmac regisetr

v1: initial version

Basic audio dmac register only supports busif from 0 to 3,
in order to use busif4 ~ busif7, extended audio dmac register
need to be used.

This patch updates H3 (= r8a7795), M3-W (= r8a7796) and
M3-N (=r8a77965) to use extended audio dmac register set.
