40780fdbeb pm: device: Get rid of device_idx_t 
It was just making the code hard to read. Also it was not following
the code guideline because the type was not telling us the sign
and size.

3dad4a068a pm: device: Get rid of z_pm_core_devices 
z_pm_core_devices was hack to set some priority between devices. It
was doing it hardcoding some devices that were the first to bring up
and the last to power down. Remove it and use the same list used to
initialize devices.

Fixes #34214

9ac646f277 power: device: Don't wake up devices unnecessarily 
Currently when the system goes to sleep it asks *all* devices that
support PM to suspend or go to a low power state, and the system wakes
up it put *all* suspended devices in active state, even if a device
was already suspended and not being used.
