tg3: Fix 57765 A0 bootcode race condition
On A0 revision of 57765 asic rev devices, the bootcode will perform some hardware operations, after the magic signature is presented, that will collide with setup operations performed by the driver. The best way to avoid the contention is to have the driver delay an additional 10 milliseconds. B0 revisions of the chip will make this workaround unnecessary.
