* dv-m68hc11.c (m68hc11cpu_io_read_buffer): Translate memory
bank window to some virtual address to read from extended memory.
(m68hc11cpu_io_write_buffer): Likewise for writing.
(attach_m68hc11_regs): When use_bank property is defined, attached
to the 68HC12 16K memory bank window.
* interp.c (sim_hw_configure): Create memory region for banked
memory.
