Power area A2VC0 was removed in revision ES2.0, cfr. R-Car Gen3 Hardware
User's Manual rev. 0.53E.
Hence remove it from the power area table when not running on ES1.x.
This is in line with the goal to:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.
