hwmon: (xgene-hwmon) use appropriate type for the latency value
The expression PCC_NUM_RETRIES * pcc_chan->latency is currently being evaluated using 32-bit arithmetic. Since a value of type 'u64' is used to store the eventual result, and this result is later sent to the function usecs_to_jiffies with input parameter unsigned int, the current data type is too wide to store the value of ctx->usecs_lat. Change the data type of "usecs_lat" to a more suitable (narrower) type. Found by Linux Verification Center (linuxtesting.org) with SVACE.
