[PATCH] Fix si(4) to use bus_space: test or the driver will be removed

[John Baldwin]

This patch fixes the si(4) driver to use the bus_space methods to access 
memory and I/O resources instead of directly calling inb()/outb() and using 
rman_get_virtual().  The patch is against HEAD but probably applies to 9 and 
10 as well.

If no one tests updates to this driver then it is not feasible to continue 
maintaining it in the tree.  In that case, it will be removed from HEAD one 
month from today.
