Subject: samples/damon/mtier: add comment for struct region_range
Date: Mon, 31 Aug 2026 07:26:09 -0700

The mtier sample defines a local struct region_range using phys_addr_t
instead of damon_addr_range which uses unsigned long.  Add a comment
explaining the rationale: on 32-bit systems with more than 4GiB memory,
phys_addr_t will be 64-bit while unsigned long is 32-bit.
