[PATCH 2/2] drivers: thermal: fix zero weighted request power

[Chia-Hao Liu]

When the product of weight and req_power is less than 1024,
the `frac_to_int()` macro causes the weighted_req_power to
become zero, it will cause granted_power to be zero.
To address issue, I add a check:
If the weight is less than 1024, frac_to_int() is not applied
to avoid setting the weighted_req_power to zero.
