Subject: [PATCH] dm: add const declaration for dm_strto* APIs

These APIs are wrap of standard strto* APIs. The first parameters in
these APIs should be declared as "const" since they have never been
changed so that they can also be used when passing a variable declared
as const char *

Fixes: e1dab512c257 ("dm: add string convert API")
Tracked-on: #1496
