pwm: sti: Use devm_kcalloc() instead of calculating the size for devm_kzalloc()

Browse Source 
Using a multiplication to calculate the size of an allocation isn't
recommended in case the mulitplication overflows. While the chance this
happens is low, preventing such an error is easy enough; so do that.
