Sachin Kamat b88a497701 thermal: step_wise: Add missing static storage class specifiers 
Fixes the following sparse warnings:
drivers/thermal/step_wise.c:153:5: warning:
symbol 'step_wise_throttle' was not declared. Should it be static?
drivers/thermal/step_wise.c:172:25: warning:
symbol 'thermal_gov_step_wise' was not declared. Should it be static?

Durgadoss R e151a202a0 Thermal: Introduce a step_wise thermal governor 
This patch adds a simple step_wise governor to the
generic thermal layer. This algorithm throttles the
cooling devices in a linear fashion. If the 'trend'
is heating, it throttles by one step. And if the
thermal trend is cooling it de-throttles by one step.

This actually moves the throttling logic from thermal_sys.c
and puts inside step_wise.c, without any change.
