Add support for the power areas in the Renesas R-Car M3-W+ (R8A77961)
SoC to the R-Car System Controller driver.
R-Car M3-W+ (aka R-Car M3-W ES3.0) is very similar to R-Car
M3-W (R8A77960), which allows for both SoCs to share a driver:
- R-Car M3-W+ lacks the A2VC power area, so its area must be
nullified,
- The existing support for the SYSCEXTMASK register added in commit
9bd645af9d2a49ac ("soc: renesas: r8a7796-sysc: Fix power request
conflicts") applies to ES3.0 and later only.
As R-Car M3-W+ uses a different compatible value, differentiate
based on that, instead of on the ES version.
