[PATCH 1/2] dt-bindings: imx8mm-thermal: Document 'nxp,reboot-on-critical'

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

Currently, after the board reaches the critical temperature, the system
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.
