[dts] [PATCH V1] tests/unit_tests_lpm: Add the size of the judgment hugepage

[Liu, Yong]

Jianbo,
Only lpm unit test required for so much memory. If there's not enough resource for some cases, this kind of cases should be taken as failed. The error reason has been included in the message, so user can choose either enlarge DUT resource and rerun or just ignore it

Thanks,
Marvin
