[PATCH for-6.0 1/2] memory: Add offset_in_region to flatview_cb arguments

[Peter Maydell]

The function flatview_for_each_range() calls a callback for each
range in a FlatView.  Currently the callback gets the start and
length of the range and the MemoryRegion involved, but not the offset
within the MemoryRegion.  Add this to the callback's arguments; we're
going to want it for a new use in the next commit.

While we're editing the flatview_cb typedef, add names for the
arguments that were missing names.
