msm: thermal: Initialize KTM interrupt mode at kernel late init level

KTM prolong KTM hotplug mitigation, cpu frequency mitigation etc. till
thermal-engine takes over. It is helping thermal runaway issues during
the boot time from KTM kernel late init level to thermal-engine
starts. Since BCL is also using KTM interface for mitigation, it
delays BCL mitigation till thermal-engine starts. Again target which
has LMH support enables Tj based mitigation very early in the boot.
So there is no risk of thermal runaway issues mentioned above.

Enable KTM interrupt mode mitigation back from kernel late init
itself. This reverts commit <07f3dcfc7f7c> ("msm: thermal: Prolong
KTM mitigation till thermal-engine takesover").
