Revert "e1000: fix sw fw sync on igb i210/i211"
This reverts commit 17da7120249bfdef877f46be5bbcb3cc01212eb9. The i210/i211 do have the SW_FW_SYNC (0x5b5c) register and this is what should be used when acquiring the semaphore. I believe the issue that this patch was trying to resolve is now resolved by properly releasing the semaphore once no longer needed.
