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
