Add dummy functions when CONFIG_POWER_DOMAIN not defined.

Signed-off-by: Peng Fan peng.fan@nxp.com Reviewed-by: Simon Glass sjg@chromium.org Signed-off-by: Anatolij Gustschin agust@denx.de ---

V3: - add 'static inline' to fix build breakage - use -ENOSYS as we do elsewhere to indicate not implemented functionality

V2: Use CONFIG_IS_ENABLED
