The region_overlap() function was removed as unused by patch
81ca755487 ("common.h: remove unused region_overlap()")
but only because the last user was prematurely removed by patch
070de908da ("ARM: remove PBL_FORCE_PIGGYDATA_COPY")
A clean reverts is not appropriate, as the previous name of
the function has been repurposed by patch
04e2aa516e ("common.h: move and rename lregion_overlap()")
