Subject: [PATCH 4/4] lib/test_printf: Explicitly add components number to %pD and %pd

After changing the default components number from 1 to 4 for %pD
and %pd, it would be better to explicitly add the number in test_printf
cases.

Add a test case of %pd5 to verify if it can be capped by 4 components.
