    ahci: increase timout
    
    For some devices, like Marvell 88SE9230, it takes more time
    to connect to the device. This patch introduces a special flag
    that extends the timeout from around 100ms to around 500ms.
    
    This change is based on the work of: Peter Eriksson <pen@lysator.liu.se>
