thermal: debug: add debug statement for core and step_wise
To ease debugging thermal problem, add these dynamic debug statements
so that user do not need rebuild kernel to see these info.
Based on a patch from Zhang Rui for debugging on bugzilla:
https://bugzilla.kernel.org/attachment.cgi?id=98671
A sample output after we turn on dynamic debug with the following cmd:
# echo 'module thermal_sys +fp' > /sys/kernel/debug/dynamic_debug/control
is like:
