Rasmus Villemoes 407feae1ca backlight: pwm_bl: Drop use of int_pow() 
For a fixed small exponent of 3, it is more efficient to simply use
two explicit multiplications rather than calling the int_pow() library
function: Aside from the function call overhead, its implementation
using repeated squaring means it ends up doing four 64x64
multiplications.
