hwmon: exynos4: move thermal sensor driver to driver/thermal directory 



This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by
driver/thermal/thermal_sys.c.  The goal is to place it in thermal folder
and add necessary functions to use the in-kernel thermal interfaces.

  The threshold and each trigger_level are set

When an interrupt occurs, this driver notify user space of

one of four threshold levels for the interrupt

When an interrupt occurs, this driver notify kernel thermal framework

Although an interrupt condition for level_0 can be set,

it is not notified to user space through sysfs_notify function.
