The power domain containing the Cortex-R7 CPU core on the R-Car V3H SoC must always be in power-on state, unlike on other SoCs in the R-Car Gen3 family. See Table 9.4 "Power domains" in the R-Car Series, 3rd Generation Hardware User’s Manual Rev.1.00 and later.

Fix this by marking the domain as a CPU domain without control registers, so the driver will not touch it.
