Lei YU 211186cae1 hwmon: (occ) Fix division by zero issue 
The code in occ_get_powr_avg() invokes div64_u64() without checking the
divisor. In case the divisor is zero, kernel gets an "Division by zero
in kernel" error.

Check the divisor and make it return 0 if the divisor is 0.

Fixes: c10e753d43 ("hwmon (occ): Add sensor types and versions")
