Remove the sysbus_add_memory and sysbus_del_memory functions. These
are trivial wrappers for mapping a memory region into the system
memory space, and have no users now.  Sysbus devices should never map
their own memory regions anyway; the correct API for mapping an mmio
region is for the creator of the device to use sysbus_mmio_map.
