[PATCH] chips: drop the register keyword and use boolean_t

[Marin Ramesa]

I noticed a variable that only receives values 0 and 1, so I'm turning 
it into a boolean. I think the code is more readable that way. Also 
drop the register keyword since I've seen Justus mention it is ignored 
by modern compilers. And I must admit I've never seen it used in a more 
modern microkernel that I worked on. Anyway, here's the simple patch:

* chips/busses.c (configure_bus_master): Drop the register keyword.
(configure_bus_device): Likewise.
(configure_bus_master): Use boolean_t instead of an int.
(configure_bus_device): Likewise.
