Each element in the array gets assigned the same value for its .base attribute. The same value also ends up as the .addr attribute of `mr` due to the memory_region_add_subregion() call. This means that all .base attributes are the same as `mr.addr`. The only usages of MemoryRegionPortio::base were in portio_read() and portio_write(). Both functions get above MemoryRegionPortioList as their opaque parameter. In both cases find_portio() can only return one of the MemoryRegionPortio elements of the `ports` array. Due to above observation any element will have the same .base value equal to `mr.addr` which is also accessible. Hence, `mrpio->mr.addr` is equivalent to `mrp->base` and MemoryRegionPortio::base is redundant and can be removed.

Add a convenience function for implementing this in the VIA south bridges. This convenience function relies on previous simplifications in exec/ioport which avoids some duplicate synchronization of I/O port base addresses. The naming of the function is inspired by its memory_region_set_address() pendant.

So far this is hardcoded such that all functions are always enabled and are located at fixed addresses. Some PC BIOSes seem to probe for I/O occupancy before activating such a function and issue an error in case of a conflict. Since the functions are enabled on reset, conflicts are always detected. Prevent that by implementing relocation and toggling of the SuperI/O functions. Note that all SuperI/O functions are now deactivated upon reset (except for VT82C686B's serial ports where Fuloong 2e's rescue-yl seems to expect them to be enabled by default). Rely on firmware -- or in case of pegasos2 on board code if no -bios is given -- to configure the functions accordingly.
