struct device has a member, dv_locators, with a comment of "our actual 
locators (optional)".
config_attach_loc will copy the locators passed in "ldesc" to that 
field.  However, most every use of that routine passes a NULL for 
"ldesc".  (only ISA and SCSIBUS pass a non-null "ldesc").

locdesc_t is disgusting and the hack in isa.c to use it is horrid.  I think 
I'd rather see locdesc_t be a struct { int len; int *locs}; and then change 
dv_locators to a locdesc_t.

Then start changing the callers of config_attach to use config_attach_loc 
with a valid ldesc.
