drivers: net: wireless: ath: wil6210: debugfs: Use 'uint64_t' instead of 'cycles_t' to avoid warnings

do_div() checks the type strictly. 'cycles_t' may be 32-bit under quite a few architectures (parisc, arm, avr32 ...). So use 'uint64_t' instead of, the related warning (with allmodconfig undr parisc):
