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)
This patch set updates H3 (= r8a7795), M3-W (= r8a7796) and M3-N (=r8a77965) to use extended audio dmac registers
R-CAR E3 only has extended register set and is already using it, rename register set name to indicate this.
--- v2: update rsnd driver to use extended register set when available rename R-CAR E3 audio dmac regisetr
v1: initial version
