AHCI: Increase link timeout to 200ms
In 73545f75b66d "ahci: wait longer for link" I increased the timeout to 40ms based on the observed behaviour of a WD disk on a Cubietruck. Since then Karsten Merker and myself have both observed timeouts with HGST disks (Karsten on Cubietruck, me on Cubieboard2). Increasing the timeout to ~175ms fixes this, so go to 200ms for a bit of headroom.
