Replace structure member "level" in power_signal_info with "flags". "level" has been used on all boards to indicate active-high or active-low levels. Addition of "flags" allows easy extension of power_signal_info structure to define various flags that might be applicable to power signals (e.g. "level"). Going forward, additional flag will be added in follow-up CLs. Also, provide a helper function power_signal_is_asserted that checks the actual level of a signal and compares it to the flags level to identify if a power signal is asserted.
