Arm SCMI fixes for v6.15
Couple of fixes addressing issues with timeout in the polling path
and device reference count imbalance detected by kmemleak.
1. The change fixes a timeout issue in the polling path of SCMI transactions
where false positives could occur if the polling thread was pre-empted,
causing it to appear as though a timeout occurred when it hadn't. The fix
ensures that the polling result is verified before reporting a timeout,
accounting for potential pre-emption or out-of-order replies.
2. It also corrects a device reference count imbalance caused by
device_find_child() during device destruction, which prevented proper
cleanup and triggered memory leaks detected by KMemleak.
