r277480, r277512, r277516:
Add inline implementations of arm bus_space_read/write_N().
Revise the arm bus_space implementation to avoid dereferencing the tag on
every operation to retrieve the bs_cookie value almost nothing actually
uses.
Use the explicit member initializer style to init the bus_space struct.
Use arm/bus_space-v6.c for all armv6 systems
Consolidate many identical implementations of bus_space to a single
common tag and implementation shared by armv4 and armv6.
Micro-optimize the new arm inline bus_space implementation by grouping all
the data the inline functions access together at the start of the bus_space
struct so that they all fit in a single cache line.
