[PATCH 06/30] thermal: cpu_cooling: standardize end of function

[Eduardo Valentin <eduardo.valentin@ti.com>]

Just for code readiness, this patch makes all functions
on this file to have a blank line before their returns.
Now, some functions follow this pattern, and others will
not have a blank line. So, this patch makes it a single
pattern.
