[PATCH 2 05/24] hpsa: change doorbell reset delay to ten seconds

["Stephen M. Cameron" <scameron@beardog.cce.hp.com>]

From: Justin Lindley <justin.lindley@hp.com>

After 3.22 firmware, PMC firmware guys tell us the
previous 5 second delay after a reset now needs to
be 10 secs to avoid a PCIe error due to the driver
looking at the controller too soon after the reset.
