From: Fabio Estevam <festevam@xxxxxxx>
Currently, after the SoC reaches the critical temperature, the board
goes through a poweroff mechanism.
In some cases, such behavior does not suit well, as the board may be
unattended in the field and rebooting may be a better approach.
The bootloader may also check the temperature and only allow the boot to
proceed when the temperature is below a certain threshold.
Introduce the 'nxp,reboot-on-critical' property to indicate that the
board will go through a reboot after the critical temperature is reached.
When this property is absent, the default behavior of forcing a shutdown
is kept.

Changes since v4:
- None. Went back to using device tree property.
