gpu: nvgpu: MISRA 21.2 fixes: __nvgpu_set_enabled()

Browse Source 
Rename __nvgpu_set_enabled() to nvgpu_set_enabled(). The original
double underscore was present to indicate that this function is a
function with potentially unintended side effects (enabling a feature
has wide ranging impact).

To not lose this documentation a comment was added to convey that this
function must be used with care.
