[PATCH v2 1/4] physmem: Rename addr1 to more informative mr_addr in flatview_read/write() and similar

[Jonathan Cameron via <qemu-devel@nongnu.org>]

The calls to flatview_read/write[_continue]() have parameters addr and
addr1 but the names give no indication of what they are addresses of.
Rename addr1 to mr_addr to reflect that it is the translated address
offset within the MemoryRegion returned by flatview_translate().
Similarly rename the parameter in address_space_read/write_cached_slow()

Suggested-by: Peter Xu <peterx@redhat.com>

v2: New patch.
- I have kept the renames to only the code I'm touching later in this
  series, but they could be applied much more widely.
