thermal: amlogic: Make amlogic_thermal_disable() return void
amlogic_thermal_disable() returned zero unconditionally and
amlogic_thermal_remove() already ignores the return value.
Make it return no value and modify amlogic_thermal_suspend to not check
the value.
This patch introduces no semantic changes, but makes it more obvious for
a human reader that amlogic_thermal_suspend() cannot fail.
