[PATCH] Various fixes to wl(4)

[John Baldwin]

This patch fixes various issues in wl(4) including:

 - Use bus_space instead of inb/outb.
 - Use device_printf() and if_printf()
 - Use callout(9) instead of timeout(9)
 - Don't hold the driver lock across sleeping actions like
   bus_teardown_intr(), subyte(), etc.
 - Don't recurse on the driver lock.

The patch is against HEAD but probably applies to 9 and 10 as well.
