Subject: [PATCH] thermal: imx: Update critical temp threshold
Increase the critical temperature threshold to the datasheet defined
value according to the temperature grade of the SoC, increasing the
actual critical temperature value of 5 degrees.
Without this change the emergency shutdown will trigger earlier then
required affecting applications that are expected to be working on this
close to the limit, but yet valid, temperature range.
