Back in the day we relied on a default value that used to be 8KiB
and it worked perfectly fine for ARC's default 8KiB page as well as
4 KiB ones, but not for 16 KiB, see [1] for more details.
So that we fixed by setting "max-page-size" if 16KiB pages are in use by
commit d024d369b8 ("arch/arc: Accommodate 16 KiB MMU pages").
But as Yann very rightfully mentioned here [2] we should be setting this
thing explicitly for all page sizes because:
1. Defaults might change unexpectedly
2. Explicitly set stuff is better understood
3. We act similarly to all settings but not only addressing some corner cases
