staging: unisys: Do not use 0 as the default bus root device number
I used 0 as the device id for the bus root, neglecting the fact that
device 0 is a valid id in Unisys's configuration. Modify this to
use UINT_MAX instead as a unique number.
As fallout from this change it was noticed the bus_no and dev_no was not
defined the same way consistently. Fix visorbus.h to use u32 there. Fix
the resulting printk warning too.
