msm: thermal: Ignore thermal bite for secure device
KTM triggers a secure watchdog bite, when temperature reaches very high
threshold. In the secure device this call is not supported.
Avoid triggering the watchdog bite, on a secure device. This bite is
triggered in KTM for debug purpose to save the software state.
In the latest hardware, the tsens controller is capable of initiating a
hardware reset after saving the software state. So this feature is used
only to print the tsens ID which crossed the very high threshold.
