Yes, but CRS happens after functional reset, D3hot etc. too not just
conventional reset.

1 second is too aggressive. We already have proof that several PCIe
cards take their time during FLR especially FPGA cards in the orders

Current code is waiting up to 60 seconds. If card shows up before that
we happily return.
