Initialization timeouts in MPT driver

[Andrew Boyer]

When using mpt with a 1068e, a bad SATA SSD can prevent all other SATA drives from being recognized.  It takes about 45s for the controller to respond to the IOC initialization request with a bad drive installed, but the timeout for SAS controllers is 30s.

> mpt0: <LSILogic SAS/SATA Adapter> port 0x5000-0x50ff mem 0xd9610000-0xd9613fff,0xd9600000-0xd960ffff irq 54 at device 0.0 on pci9
> mpt0: [ITHREAD]
> mpt0: MPI Version=1.5.20.0
> mpt0: Firmware version=1.30
> mpt0: mpt_wait_req(6) timed out
> mpt0: port 0 enable timed out
> mpt0: mpt_enable_ioc: failed to enable port 0
> mpt0: unable to initialize IOC

The IOC initialization timeouts on linux are ten times as long as in BSD (300 or 30 seconds vs 30 or 3 seconds), and linux is able to see all of the good drives.  Changing the mpt timeouts to match linux allows freebsd to see the good drives, too.

Thoughts?
