pwm: lp3943: Fix an incorrect type in lp3943_pwm_parse_dt()
The return value from the call to of_property_count_u32_elems() is int.
However, the return value is being assigned to an u32 variable
'num_outputs', so making 'num_outputs' an int.
./drivers/pwm/pwm-lp3943.c:238:6-17: WARNING: Unsigned expression compared with zero: num_outputs <= 0.
