Thermal: Refactor thermal.h file
This patch rearranges the code in thermal.h file, in the following order, so that it is easy to read/maintain. 1. All #defines 2. All enums 3. All fops structures 4. All device structures 5. All function declarations Signed-off-by: Durgadoss R <durgadoss.r@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
