Increase timeout in Atheros HAL

Summary

It turned out, that some models of the Atheros PCIe
adapters (e.g. AR983x family) may fail to attach
due to insufficient timeout value.

Thanks for a brief response. It happened on various Marvell Armada 38x boards + different AR983x cards. With this small fix all init problems were gone.
