While using the libflashrom API to read specific regions there is no currently no general way to find the offset into the read buffer of the expected region. flashrom_layout_include_region() probably should have returned the region offset and size if it was included. However to avoid a change in API signature we can instead hoist up get_region_range() into the API to be called after. BUG=b:207808292 TEST=`make` && tested in porting cbfstool use-case.
