scsi: smartpqi: Add ctrl ready timeout module parameter
Allow user to override the default driver timeout for controller ready.
There are some rare configurations which require the driver to wait longer
than the normal 3 minutes for the controller to complete its bootup
sequence and be ready to accept commands from the driver.
The module parameter is:
ctrl_ready_timeout= { 0 | 30-1800 }
and specifies the timeout in seconds for the driver to wait for controller
ready. The valid range is 0 or 30-1800. The default value is 0, which
causes the driver to use a timeout of 180 seconds (3 minutes).
