NVIDIA: SAUCE: net: phy: aquantia: Poll for valid FW ID.

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2072591

Firmware ID will be shown as 0xFFFF if firmware is not yet loaded.
So, add this too in the exit condition of the poll so that poll
won't exit for 0xFFFF and continues till init completion with valid
FW ID.
