[PATCH] samples/damon/mtier: use damon_addr_range consistently

[Enze Li]

The DAMON provides struct damon_addr_range for unified address range
management.  However, the mtier sample still defines a local struct
region_range with an identical layout (start and end as phys_addr_t) and
mixes its usage with struct damon_addr_range in
damon_sample_mtier_build_ctx().

This patch removes the local struct region_range and changes the
parameter type of nid_to_phys() to struct damon_addr_range.
