[U-Boot] [PATCH 5/8] ahci: extend data io wait to 10s

From: Mark Langsdorf <mark.langsdorf at gmail.com>

The AHCI driver currently waits 5s before timing out when sending a
data command to a drive. Some drives take upwards of 8s to respond to
the initial data command while they're spinning up. Increase the
data io timeout to 10s so that those drives can be found on initial
scsi scan.
