[PATCH 7/8] target/i386: Use memory_region_add_subregion() when priority is 0

[Philippe Mathieu-Daudé]

It is pointless to overlap a memory subregion with priority 0.
Use the simpler memory_region_add_subregion() function.

This patch was produced with the following spatch script:

    @@
    expression region;
    expression offset;
    expression subregion;
    @@
    -memory_region_add_subregion_overlap(region, offset, subregion, 0)
    +memory_region_add_subregion(region, offset, subregion)
