portio_list_add_1() creates a MemoryRegionPortioList instance which holds a MemoryRegion `mr` and an array of MemoryRegionPortio elements named `ports`. 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.
