Available starting with Mali v12, the SHADER_PWRFEATURES register is a
32-bit register that contains a single bit so far. This bit flag
indicates whether the RT cores should be powered up or not.

The name "SHADER_PWRFEATURES" (as opposed to "SHADER_POWER_FEATURES") is
taken directly from official hardware documentation.
