[PATCH 2/3] cxacru: Reduce initialisation delay

[Simon Arlott <simon@fire.lp0.eu>]

Since card status updates appear to only occur every second, a delay
of 1000ms on startup may not be sufficient - change to 1500ms.

The long delay of 4000ms is likely to be related to the time required
for the ADSL line to come up - the driver should not need to do this.

Overall delay when loading firmware will change from 5000ms to 1500ms.
