Petr Oros b537752e6c ice: wait 5 s for EMP reset after firmware flash 
We need to wait 5 s for EMP reset after firmware flash. Code was extracted
from OOT driver (ice v1.8.3 downloaded from sourceforge). Without this
wait, fw_activate let card in inconsistent state and recoverable only
by second flash/activate. Flash was tested on these fw's:
From -> To
 3.00 -> 3.10/3.20
 3.10 -> 3.00/3.20
 3.20 -> 3.00/3.10

Reproducer:

Reboot doesn’t help, only second flash/activate with OOT or patched
driver put card back in consistent state.
