ath79: speed up ath9k-eeprom extraction
This is a simple copy of ipq40xx: speed up ath10k-caldata extraction commit a69e101ed1169f562fc030a783cd997d3f066b16 Tested on DIR-825-B1 3768+0 records in 3768+0 records out real 0m 11.90s user 0m 0.03s sys 0m 9.94s 1+0 records in 1+0 records out real 0m 0.03s user 0m 0.00s sys 0m 0.03s With this change eeprom extraction is fast enough to get working Wi-Fi after initial install.
