The type of bus_space_tag_t is now a pointer to bus_space_tag structure, and the bus_space_tag structure saves pointers to functions for direct access and relocate access. Added bsh_bam member to the bus_space_handle structure, it saves access method either direct access or relocate access which is called by bus_space_* functions. Added the mecia device support. If the bs_da and bs_ra in bus tag are set NEPC_io_space_tag and NEPC_mem_space_tag respectively, new bus_space stuff changes the register of mecia automatically for 16bit access.
