From: Benjamin Bara <[email protected]>
Implement the new get_active_protections() op. This helps to find out if
a monitor is enabled and the DT is unaware of it. This could result to
an invalid state, as the !PWR_OK state might be triggered if the
regulator is turned off while the monitor stays active.
