ahci: more robustness against flaky devices

- if supported, override BSY/DRQ flags and start the port anyway if it
  times out with DET=3h status during device detection;
- no longer rely on the device signature to be set; unless a valid
  signature is obtained, try both ATA and ATAPI device identification.
