mm/damon/core: receive addr_unit on damon_set_region_biggest_system_ram_default()

damon_find_biggest_system_ram() was not supporting addr_unit in the past.
Hence, its caller, damon_set_region_biggest_system_ram_default(), was also
not supporting addr_unit. The previous commit has updated the inner
function to support addr_unit. There is no more reason to not support
addr_unit on damon_set_region_biggest_system_ram_default(). Rather, it
makes unnecessary inconsistency on support of addr_unit. Update it to
receive addr_unit and handle it inside.
