Add a macro to check for sufficient pointer alignment in bus.h context,
...
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

* Pass the bus tag instead of just the cookie to all bus space methods.
...
* In the bus tag structure, keep a reference to the parent bus.
* Express all bus space methods as inline functions in stead of macros
and use the parent bus tag reference to find the nearest "upstream"
bus that implements the method.
