[ Upstream commit b5eb730e031acaba2d25e8f522ac5966a70885ae ]

The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018)
renamed the A2IR2 and A2IR3 power domains on R-Car V3M to A2DP resp.
A2CN.

As these definitions are not yet used from DT, they can just be renamed.

While at it, fix the indentation of the A3IR definition.

Fixes: 833bdb47 ("dt-bindings: power: add R8A77970 SYSC power domain definitions")
Fixes: bab9b2a7 ("soc: renesas: rcar-sysc: add R8A77970 support")
