Added option to use system channel for setup wakeup from soft off. In Lilium there is insuficcient grtc channels and no spare channel that can be used as wake up source. Added function to disable all grtc channels, except the one used for wake up to be able to enter soft off stated on local domain (disable uncexpected grtc wake ups).

Enabled LATCH reading on sw1 this need additiona REATAIN bits manipulation. Changed console to be handled automatically, otherwise there are some unknown characters when console is suspended. Removed obsolete configs. Signed-off-by: Łukasz Stępnicki <[email protected]>
Low power comparator can be used as wake up source for nrf54h20. Using LPCOMP as wakeup needs global power force when entering system off, this is handled in sysctrl. Signed-off-by: Łukasz Stępnicki <[email protected]>
This is new method of entering system off state. Local domains do not shut down immediatelly but rather go to deep sleep (idle or s2ram) and waits for other domains to go to system off. This enable option to go back to normal operation if there is something blocking system off. For example application is not yet ready to soft off and wakes up radio. This also enables GRTC to be used with system methods like k_sleep to wake up from system off at scheduled time. Signed-off-by: Łukasz Stępnicki <[email protected]>
