pwm: meson: fix handling of period/duty if greater than UINT_MAX

Browse source

commit 87a2cbf02d upstream.

state->period/duty are of type u64, and if their value is greater than
UINT_MAX, then the cast to uint will cause problems. Fix this by
changing the type of the respective local variables to u64.
