This patch modifies TMU controller to add changes needed to work with
exynos5440 platform. This sensor registers 3 instance of the tmu controller
with the thermal zone and hence reports 3 temperature output. This controller
supports upto five trip points. For critical threshold the driver uses the
core driver thermal framework for shutdown.

This patch adds support to handle multiple instances of the TMU controllers.
This is done by removing the static structure to register with the core thermal
and creating it dynamically for each instance of the TMU controller. The
interrupt is made shared type to handle shared interrupts. Now since the ISR needs
the core thermal framework to be registered so request_irq is moved after the core
registration is done.
Also the identifier of the TMU controller is extracted from device tree alias. This
will be used for TMU specific initialisation.

Commit f1a18a10 "Thermal: CPU Package temperature thermal" had code
that did a get_online_cpus(), run a loop and then do a
put_online_cpus(). The problem is that the loop had an error exit that
would skip the put_online_cpus() part.

In the error exit part of the function, it also did a get_online_cpus(),
run a loop and then put_online_cpus(). The only way to get to the error
exit part is with get_online_cpus() already performed. If this error
condition is hit, the system will be prevented from taking CPUs offline.
The process taking the CPU offline will lock up hard.

Removing the get_online_cpus() removes the lockup as the hotplug CPU
refcount is back to zero.

This was bisected with ktest.
