power: Add flags parameter to power_signal_info
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.
