v1->v2:
Michael suggested to wait for the in-flight DMA to complete at probe
stage. So give up the old method of trying to reset chip at probe
stage, take the new way accordingly.

Thanks a lot!
net device up stage. This will cause
hardware iommu handling failure on bnx2 device. And its resetting relies
on firmware. So in this patch move the firmware requesting code to earlier
bnx2_init_one(), then next call bnx2_reset_chip to reset device.

ntry calling to __map_single calling, the principal should be
similar.

red to net device up stage. This will cause
hardware iommu handling failure on bnx2 device. And its resetting relies
on firmware. So in this patch move the firmware requesting code to earlier
bnx2_init_one(), then next call bnx2_reset_chip to reset device.
