Describe the bug
On cc1352r1_launchxl, the system fails to enter soft_off state (what used to be known as deep sleep 1):

*** Booting Zephyr OS build v2.5.0-rc1-106-g2712d74cdcbf  ***

cc1352r1_launchxl system off demo
Busy-wait 5 s
Sleep 2000 us (IDLE)
Sleep 3 s (STANDBY)
Entering system off (SHUTDOWN); press BUTTON1 to restart
ERROR: System off failed

To Reproduce
Steps to reproduce the behavior:

  1. cd samples/boards/ti/cc13x2_cc26x2/system_off
  2. west build -b cc1352r1_launchxl
  3. west flash
  4. See error

Expected behavior
The system should enter soft_off state.

Impact
Cannot enter soft_off power state to save power when desired.

Environment (please complete the following information):

soc: cc13x2_cc26x2: add support for soft off power state
b738ef0 
The soft off power state should be supported as it is closest to what
used to be deep sleep state 1, which corresponds to the device off
state supported by hardware.

Fixes zephyrproject-rtos#31727.

In the last step of the example, the system should go into soft off
state in order to match the original intent in the example to go
into the hardware's SHUTDOWN mode.

Fixes zephyrproject-rtos#31727
