I can I suppose, sure.

T-Head SoCs feature separate power domains (power islands) for major components like the GPU, Audio, and NPU. To manage the power states of these components effectively, the kernel requires generic power domain support. This commit enables `CONFIG_PM_GENERIC_DOMAINS` for T-Head SoCs, allowing the power domain driver for these components to be compiled and integrated. This ensures proper power management and energy efficiency on T-Head platforms. By selecting `PM_GENERIC_DOMAINS`, we provide the necessary framework for the power domain drivers to function correctly on RISC-V architecture with T-Head SoCs.
