sensors: dts: Assert special wakeup on idle cores while reading temperature
In P9, when a core enters a stop state, its clocks will be stopped
to save power and hence we will not be able to perform a scom
operation to read the DTS temperature sensor. Hence, assert
a special wakeup on cores that have entered a stop state in order to
successfully complete the scom operation.
